Vodafone Sure Signal review

 Review: April 2012  

Rating: 4 stars

In a nutshell: The Vodafone Sure Signal connects to a fixed broadband line in your home or office and provides a reliable Vodafone 3G voice and data connection. A must-have gadget for everyone working from home.



Getting a good mobile phone signal is a problem a lot of us have to face, whether it's from home or office, so the Vodafone Sure Signal appears to offer a perfect solution. Set up a Vodafone Sure Signal, and you have a 3G transmitter & receiver wherever you want, as long as you connect it to a fixed-line broadband modem or router. OK, so you can't carry it around with you, but you can set it up in your home or office and it will provide you with 3G coverage in the building. Data is transmitted via your fixed broadband connection, providing you with a full voice and data service that should be indistinguishable from a normal 3G service.

We tested the device in a house located far from any towns, and with thick stone walls, where mobile reception usually varies between zero and one bar and where 3G has not been seen in living memory. We used a BT Business Total Broadband 8Mbps connection and a BT Business Hub.

Setting up the Sure Signal was easy enough, once we realised that the instructions supplied by Vodafone were incorrect. Start by logging into the Vodafone website with your account username and password and click "Register your Sure Signal." Enter the postcode of the location where the device is to be used, the serial number (printed on the back of the device), the floor level on which you'll be installing the device and register a list of mobile numbers that are authorised to access the service (so passers-by and neighbours won't be able to piggyback on your 3G signal.) The list of authorised numbers can include any 3G devices with Vodafone SIM cards, including mobile broadband USB modems. Up to 32 numbers can be registered.

Once you've completed this registration process, you connect your Sure Signal to your modem using the supplied ethernet cable (you'll need a spare ethernet socket on your modem or router), plug it into the mains and switch on. The device then powers up and can take up to an hour to configure itself. In our test it took 30 minutes. You should only need to do this once, as the device stays on 24/7.

Once fully configured, any registered device can make calls or transmit data over the 3G network. Over a period of one month testing, we found the service to be very reliable, although not 100% solid. In the room where the Sure Signal was installed, registered mobiles showed a full 3G signal all the time. Call quality was excellent, although one call was dropped and on one occasion the 3G network disappeared, which was solved by rebooting the Sure Signal device. Data transfer speeds were usually around 0.5MB per second (4Mbps) for file sizes up to 14MB. This was probably a limitation of the fixed broadband connection.

The maximum range of the device seems to be about 40 metres, which is enough for a typical house or a small office. At a distance of 20 metres, with three intervening walls, the 3G signal dropped to about two bars and data transfer slowed by 50%. We didn't test the device with multiple phones, but Vodafone say that the maximum number of simultaneous users is four.

You may be worried about the health implications of installing a mobile transmitter in your home or office, but the Sure Signal emits a lower level of electromagnetic radiation than a standard wireless router, which in turn is much less than a normal mobile phone antenna. This is why the range of the device is so limited.

We found that the Sure Signal did the job it was intended for. Whilst the signal wasn't bullet-proof, it was probably as reliable as the kind of signal you'd enjoy in most city centres, with only one call lost in a period of one month. Data transfer was very fast and reliable. If you live in the country, or in a basement or other blackspot, then the Sure Signal will solve your reception problems. And if you work from home or have a small office, then the benefit of owning the Sure Signal greatly outweighs its cost. We'd have awarded it 5 stars if we hadn't dropped that one call.

What is the annual running cost electricity ?

Don't you actually mean 'the benefits of sure signal greatly outweigh the cost' rather than the other way around?

Asked by Jon L from UK on 12th Jun 2016
Thanks for the review. I'm thinking about switching networks and this device, living in a house with poor indoor signal.

Thank you, Jon. That is exactly what we meant! We've changed it now.

I am in an area where Vodafone offer the least worse service, so no worthwhile choice of provider.
Then someone told me about SureSignal, which transforms reception throughout most of the house.
Reliability is satisfactory, but only for the duration of the guarantee and shortly after that has expired,they all follow suit. I think my fourth is going the same way. If I am lucky, I may get a discount from Vodafone on yet another replacement.
What a business model. Charge the earth for inadequate service, then sell a piece of kit to make up for their failings and keep selling replacements every eighteen months.
It's not as though I live in a totally isolated area, although it is only a hamlet of about thirty properties. Roll on the arrival of fibre, due for completion in September. Then I can wave goodbye to Vodafone and BT!

I live in a 4g area but after having work done on the house. Soundproofing, fireproofing ect, my signal was only 1 bar or if lucky maybe 2. Nearly everyone I called said I was breaking up or calls were dropped. A week ago I obtained a sure signal and hey presto I now have a full signal and can enjoy my calls anywhere in the house without having to press up against a window.

Sure Signal installed and apparently working properly, except ... I can't call other phones that are registered to my Sure Signal net while we are both within the signal radius of that Sure Signal unit. OK, I can use some other means to communicate with them when we are on the same wi-fi net but being Sure Signal "buddies" seems to block normal phone comms with them.

I'm not really sure what this device is or what it's benefits are. For one, I've set it up and registered it and all the lights are indicating it's working. I have a working fast broadband connection but the device has made absolutely no difference to my phone. I'm still sitting with the little 'H' at the top of my screen. Secondly, even if it did work, what exactly is it doing? I'm paying for data which is actually going through my broadband and therfore not using mobile data at all. I can just switch to Wi-Fi when at home. Why would I connect to a device which uses my broadband connection when at the same time it's using up my mobile data allowance? This sounds like the most useless and pointless device I've ever heard of. I can understand it boosting a phone call but we have land lines in our homes and office don't we? Seems like a waste of money.

Reply by S21 from UK on 5th Feb 2017
Hi Lawrence, the purpose of the Sure Signal is to boost your reception for voice mail and texts. It will make no difference to data, since you are already connected to Wi-Fi, and therefore you don't pay for your data usage.

I have to say THIS WORKS!
After maintenance repairs to our nearest mast we ended up with very low signal in most of the house and in places none. After hours on the 'chat' I ended up purchasing the SS and getting Vodafone to credit my account for its value - this was hard work, but by taking a printed copy of an online chat, where the advisor agrees my need for the SS, our local store spoke to vodafone to confirm both my online chat and purchase.
We have 3 IPhones- the 6, 5,and 4- the 6 maintains a constant full signal and the 3 and 4 manage a 50-60% signal - all soo much better than no signal before.
I don't agree with their 30 meter range- maybe 15/20, but we do have thick walls and lots of metal structures within the building.
No issues registering or connecting the phones and we have had this connection over a week now.

Pleased with the results!

Seeing all the bad words about Sure Signal -

Thank goodness for Sure Signal!!!!!
I live out in the sticks : Vodafone recently texted to say that they had "tweaked" the nearby towers to improve coverage - which meant that our signal went from very low to none at all. So now we rely entirely on SS.

With both Netgear and Technicolor routers, setup is fairly straightforward (though a bit long-winded) - no special settings needed for the routers. It is a bit alarming that the unit takes so long to get going - worries that there might be something wrong, but it gets there in the end!

Good features -
* Excellent signal throughout the house and over much of the (large) garden.

Annoying features -
* The time the Mk2 model can take to get going after a broadband dropout.
* The fuss about postcodes if you get given a different IP address after a dropout (Vodafone thinks you have moved and keeps texting and emailing until you reset the postcode).
* Data transferred over the SS connection comes out of your monthly phone data allowance.

Note that the Mk1 SS only takes 3 or 4 minutes to start up from cold - MUCH better than the Mk2.
(I have one of these in my workshop which is a long way from the house).

Had poor signal in house with only a few spots where you could make/receive calls. Complained many times to Vodafone and eventually they sent me a Sure signal f.o.c. Installed as per instructions and registered it online. It did take several hours to set itself up, however after a full reboot, was working within 40 minutes. Excellent 4g signal on all devices registered too it now and no more dropped/un-connecetd calls. Great job, only question I have is why would Vodafone not listen everytime I rang to complain about poor signal saying according to their coverage map my signal should be fine. Why would I lie to them! Only offered me the Sure signal when I rang and said I was leaving them, after 12 years.

Anyway, I found it pretty straight forward to set up and am now well happy with the device :-)

I have a Vodafone sim only contract and can only get one bar of GSM or 2G signal where I live. I do however have BT Infinity with a Home Hub 5 Wireless router. Plugged the Sure Signal into the router, went on line, logged onto "My Vodafone" and registered my mobile number in the Sure Signal section. 30 minutes later, voilą - a perfect, strong 3G signal that after 6 months has not dropped a single call. I do not work for Vodafone but feel a balancing review is necessary amongst all the negatives.

I am having problems installing sure signal -

I am going round in circles between BT and vodafone;
After approx 6 hours on hold/ in queues / passed from one tech support person who knew nothing to another....
Finally discovered that BT have a firewall that does not allow sure signal to get through;
They need a port number, however Vodafone tech support seem unable or unwilling to provide this - they keep giving me lists of numbers that dont mean anything or fit the required formats in BT site;
as a technological novice - I am unable to install;
And this is frustrating as vodafone will not take the product back as I have had it for approx 1 month (its taken this long to get this far)
I AM NOT impressed.

Useless. After 4 phone calls and a re register with Vodaphone told me to contact orange (with their router) Again after three different phone number endless waiting time , the operator told me orange would not reset the ports setting as not their job, told to go back to Vodaphone.
Just a waste of money.

The Sure Signal maybe promise a lot and perhaps it can work under the right circumstances but ... after owning one for 2 days I am still not able to get it to work.

The installation guide promises very simple set up. According to the installation guide, you register it online; plug into your router; power up and you are done.

The reality is a million miles away. What they do not tell you, is the chances of it working following these simple steps is close to ZERO.

Once you contact technical support, the real trial begins.

Vodafone will tell you to set all manner of port forwards on your router; something like 10 ports, a mix of TCP and UDP protocols need to be forwarded to the sure signal; whoa I hear you say, what does all that mean - spend many hours trying to figure out all that! Basically, for an averagely literate computer user, this is still complex stuff and requires that you get into your routers advanced configuration and risk opening your home network to the whole world if you make a mistake.

Even after doing this it still does not work - ah, perhaps your ISP is not on the Vodafone whitelist - whoa, what does that all mean. Again, you are in the realms of internet and network protocols.

Vodafone request traceroutes, ping tests, speed tests details of your IP be posted PUBLICLY!

I wish I could report that even after all that, the trials and tribulations were worth it - sadly I cannot. After 2 days, still no working sure signal despite following all the guidance and advice.

I am sure under the covers, the technology is okay but in a world of consumer devices this falls very very short of the plug and play appliances we are all so used to. Vodafone do not help matters by making their own servers that service the sure signal so hidden from the web that individual ISPs must be permissioned on their firewalls that they use network methods really not appropriate to domestic use.

It's a shame.

All the users here are muppets, I'm sorry, but you are. I worked for years in Tech support and you people are the absolute worst people to deal with. You're completely and utterly inept, so you blame the equipment.

A monkey could set up a Suresignal.
Plug it into a power socket.
Plug the supplied ethernet into the DSL socket on the Suresignal
Plug the other end into your router.
Go online and register for a voda account
Register your sure signal and phone numbers.

if you can't do any of the above, then I can only assume you must carry a card around with you saying "Breath in, breath out".

I've worked in tech for years and setup several of these before. The setup isn't the same for all router so before you go calling people muppets I would get back in your box and wind your neck in. The auto config settings on the sure signal only works with some routers (for example: BT home Hub). A vast majority you'll need to open inbound and outbound traffic which to someone of your greatness...Cough! is easy to do. it isn't for some others.

Chronically difficult to set up unless you're a tech wizard. I'm not, but my home uses three Vodafone mobiles. I got a friend to help but I'm not convinced this gizmo has improved my reception.

Advertised as "Sure Signal", it's anything but!

Regular dropping of calls and poor voice quality when it does connect. To be fair I live well out in the sticks and I think the issue is a combination of poor broadband speed and a lack of IT knowledge on my part. This is exacerbated by a support team that appear to operate to a script and give a fixed response to a given issue.

Overall not impressed as all of this limits my ability to work from home when I can't connect to conference calls on a reliable basis.

We are very disappointed and haven't been able to register for a vodaphone account let alone register the sure signal as we don't get a mobile signal to receive the text with the code. Wish we hadn't bothered. Spent far too long using live chat, not successful and drove a few miles to try and pick up the text.

Any advice gratefully received!

Rural area. Without sure signal two bars in one spot in the house standing by window. With sure signal four bars but only in the same room as the unit is plugged in. A straight forward automatic setting up procedure with a text from Vodafone to verify connection completed. At least I can now send and receive text from home, but at a cost of £100 for the unit to work in only one room makes it an expensive option.

Hi who did you buy from, you were conned the unit cost is £69.00.

It should be noted that Vodafone Sure Signal will drop calls if your internet DOWNLOAD SPEED drops below 0.50 mb or even 1.0 mb so you need to do
speed test.net to keep eye on your I.P whoever it is.

Another thing Vodafone (tech support) say we only garantee the product for 12 months from sale and registration after that your on your own
"is this consumer right legal ? " after all you are paying for a service of 3G in 2014 from them Whos responability is it to provide that monthly or contract period ? Any body checked this out yet what chance of you getting 4G in 2020.

For your information Vodafone are on Version 3 some customers are authorised by LEVEL 3 team head office in Newbury to free replacements on renewal after contract negotiations .other than that pay up and move on it gets you there only for now though.
