And at times, I have bought a phone from elsewhere cheaper than from O2, but got them to put it on O2.
Hope you enjoy the Community, welcome.
I have been with O2 for many years, first as a PAYG customer and the last 6 years on contract. I stay with O2 because I get good coverage and good service.
No they are not the cheapest for phones but service and coverage outweigh cost for me.
Sim only for me but I will definitely be looking elsewhere for cheaper deals when my contract ends. O2 gives me decent coverage but I get better with EE and Three, I haven't tried Vodafone however @Mag1
