Anyone else having this problem? Phone on pay monthly deal. O2 store & customer services unable to fix. Has had new SIM card.
Can make calls to other networks and browse web....just not receive calls or texts from non-O2 phones.
Something similar happened when I changed from another network. If you call Customer Support they should be able to submit a fix request or do it themselves. Well hopefully you can get someone helpful as the last time I telephoned O2.
