I've just been made redundant so amongst other things I need to sort out my own mobile phone contract (or PAYG). Up until now I've had a company provided Vodafone SIM, but the signal is poor where we live, pans I often get dropped calls before I even get to answer them. But their online coverage checker says I should be fine. So I am considering other networks but am wary of what their maps say too. I tried a virgin SIM which wasn't good, so I think that means O2 would be bad too? And three wasn't much better. So does that only leave me with orange/EE or stick with VF? Do any shops like Carphone Warehouse loan out SIMs from different networks so you can see which has the best signal before buying?
