Will Cel-Fi RS2 work for BT Mobile?


BT Mobile is an MVNO (Mobile Virtual Network Operator). BT mobile in the UK runs on the Vodafone UK network. (Another example of an MVNO is Virgin Mobile, which runs on the T-Mobile UK network). Basically if you had a Vodafone UK booster it would help a BT mobile customer.

At the moment we are still working on getting permission to make Cel-Fi available on Vodafone UK.

Many boosters providers claim that there’s a loophole in the Ofcom policy stating that signal boosters are legal if they don’t interfere with other networks and their boosters abide that rule. Is it true?


The Ofcom rules are:

1)The boosters must not interfere with other networks.

2)The boosters remain within the license conditions of the mobile network which they boost – this means that the mobile network must be able to control them (turn them on and off) and the boosters must automatically configure themselves so as to never cause harm to the network.

Some products may claim to meet (1) but no product other than Cel-Fi can meet (2).  Incidentally you may not have been aware, but all Cel-Fi RS2 devices sold in the UK can be turned off by the network if they set certain parameters to be sent over the air.

The loophole in the Ofcom policy is that it is not illegal to sell mobile phone signal boosters that meet only (1) however it is definitely illegal to actually use them!

Ofcom publish UK Mobile Services Map 2011


I’m sure you are quite familiar with the coverage maps already as these can be found at every mobile network provider’s website. Today however we dug into the Ofcom website and found yet another map but this one is claimed to be prepared by administrative authority.

The map shows the percentage of geographic area or/ and premises over which all operators have 2G coverage (outdoor reception). You can also see the percentage of geographic area or/and premises over which all operators have 3G coverage (outdoor reception) and in this case the map is pretty much all pink. This means that most of the country has no reliable 3G signal. You can click on the region you’re interested in to obtain more specific information about either 2G or 3G coverage in that area.

Take a look yourself and tell us via twitter @CelFiUK whether it’s true for your area. The map can be found here.

It took less than 2 minutes to install and I had the full 5 bars on my phone. No drilling, no cabling and full HSPDA performance onto my phone.

The Cel-Fi is true to its maker’s promises. It’s relatively cheap considering the returns, and extremely easy to set up – the plug-and-play design means you can have it up and running in less than five minutes.

It will constantly search for the best available signal in an area up to 13000 square feet, so you should see your one bar of coverage turn into five.
The booster may even have a beneficial effect on the battery life of your smartphone, as constantly searching for a signal can drain the juice from your battery.
Because it is wireless, there are no ugly cables, and installation is simple.

The system, by all accounts, works well and only takes five minutes to install. It does what it says on the tin: you get decent 3G coverage, allowing you to browse the web on your phone, download apps, browse sites, call, etc.
