Currently with EE, very poor signal in the two areas I frequent. I was planning to get a few PAYG Sims from different vendors to see if other networks are better, but given you have to actively check. I was wondering if anyone has used an app that logs phone signal. Plan was to install the app on my main phone with the EE Sims and a spare phone with the PAYG Sims and turn on some kind of automated logging, so I could go back later and see how good / bad each network was at specific times.
