It’s not just O2! I use Vodafone with my company phone and their network reliability & coverage has been absolutely appalling lately. I work from home a lot & for around 3 weeks in late August/ early September I had no reliable signal at all & ended up purchasing a “Sure Signal” box from them which uses my home broadband connection to guarantee a 3G signal to my phone. (This affects my connection to my company network so really doesn’t help that much anyway!). I’ve since heard that they’ve been upgrading my local mast to 4G, but no-one at Vodafone has officially confirmed this with me.
This problem isn’t just where I live in West Yorkshire either. I’ve just been involved in a project to roll out smartphones & a custom app for 200 field service engineers in the UK & the number of people complaining about poor network coverage all over the country has been suprising.
Vodafones service has been pitiful throughout these problems too. If anyone knows of a reliable mobile network provider right now, I’d be very interested to know who it is 😕
