As per title.
When VM were with EE, had 5 bars signal almost 100% of the area.
Then VM move3d over to Vodaphone and signal strength dropped from 5 bars to 3-4 at best, and sometimes no 4g at all, and phone dropped back onto 3g, and started getting no mobile internet in areas where it was 4g on EE..
VM sent me 2 new sims, and I was askes to check them in another phone. All the Voda sims were poor, in both handsets I have, and I have struggled along on these for a while, rather than swap provider, hoping that the O2 move might sort it out. (as repeatedly suggested by staff!!)
Sadly, it's WORSE. no signal at all in several places where I visit, and only 3g (E) signal in others. 4G seems to be almost non existent, rarely getting anything above 3 bars when I do.
Paying for 4G, getting 3g if I'm lucky. (and yes, O2's signal strength app speaks with forked tongue!!) telling me I have good signal everywhere!!
Spare phone currently on '3', and gets 4G 5 bars everywhere, in either my spare or my personal handset, yet the O2 gets 3G mostly, 4G sometimes, in both, so it's NOT the handset!!
Like many, many others reporting the same thing, think it's time to go back to either EE or 3, as both have vastly superior coverage than Voda (which is poor) or O2 (which is even worse!!)
Considering I have a Nokia new X10, and can't get decent 4G from O2, yet my older Blackberry gets 4G on '3' in more locations than the Nokia/O2 does!!
VM went from EE, (great signal) to Voda, (average signal) to O2, (poor signal) yet the price goes up and up!! Obviously, this isn't going to get any better, so time to move on.....
