Phone networks - signal difference?

[MimiThePink]

Is there much difference now between the mobile networks? Considering a move to O2 but I know years ago a colleague used to rant and rave about their coverage - has anyone found a dramatic difference?

EE has the best coverage but some areas only work with one provider.

That's a good point, will look up coverage maps - thanks. I don't know how much I trust them though!

In practice I have found a very definite difference between my previous provider ID Mobile (who use the Three network hardware) and Lebara (who use the Vodafone network hardware) - I have a campervan and travel around the UK to anything between 20-30+ different locations every year. I noticed that my wife's much older mobile phone (my old Motorola M4 Plus) using Lebara consistently uses to get more of a usable signal than my much newer (Redmi Note 10 Pro) mobile when I used ID Mobile - ID had the much better deal for data - allowing me to carry over unused data from one month to the net but honestly - it meant nothing when I couldn't get a signal. I did wonder if it was just that my handset hardware wasn't as good as my old one - unlikely I thought but I switched to Lebara and have consistently seen much better signal strength with them compared to what I had with ID Mobile.
