Do Tesco Sims Work In O2 Phones. Only thing i noticed is with the Tesco sim in it Tethering disappears due to them not supporting it obviously. I have no affiliation whatsoever with O2 or any subsidiary companies.

If youve got a Tesco Mobile phone and you want to put another networks SIM card into it you need to find out whether your Tesco Mobile phone is unlocked. Tesco Mobile uses the O2 network but they are an independent company. In fact i lent my phone ot a mate on Voda for a few months.
Youll get access to 5G 5G plan required 4G 3G and 2G in all the places available with O2.
We work off different netowrk IDs and different locks in the same way as the other networks. If youve got a Tesco Mobile phone and you want to put another networks SIM card into it you need to find out whether your Tesco Mobile phone is unlocked. Provided the SIM works and the phone you have is unlocked then you can use any SIM card. Its the same network its just the billing thats different.
