I have 2 phones one with an O2 sim in it (which i use mostly) and one with a Tesco sim in it! Anyway, I get the 300 free txt and 300 free wap thing with o2 and with tesco i find it cheaper to call other networks. I also really like virgin but no-one in my family have it making calls 35p a minute, i want to try and just have 1 sim but i like tesco for their call prices but o2 for their free texts and wap which neither virgin or tesco have, what should i do?
