Tesco sim in an o2 phone

    Good morning all
    Does anybody know if I buy a Sumsung J3 from o2 today will a Tesco sim card work in it ?


    It should. But ask O2 for confirmation just before u buy it.

    not sure but an o2 SIM will not work in a locked Tesco phone, just tried it

    Should be absolutely fine since my old phone was network locked to o2 but I encountered zero issues in swapping out Tesco and GiffGaff SIM cards (they're both virtual networks that rely on o2 infrastructure) without paying to unlock the handset first.

    I've rang o2 and they can't give me a straight answer..I'm buying it as a gift for someone who wants to stay on Tesco mobile. Tesco are selling the phone for £149 and o2 are selling it for £109 with a £10 top up.

    I'm of the thought that it will work fine that way round but an o2 SIM may not work in a Tesco payg phone

    You can unlock it for around a £5 on ebay…961?hash=item1a0a0f7d41:g:CNYAAOSwvg9XdtDa
