my SIM card is ending, I need a new one, but I don't know if there is things in the contract that are not Islamic, and I probably won't understand the contract if I read it, and it is probably a very long contract. Should I get the SIM card? there will be harship without it جزاكم الله خيرا

Ustadh AbdulAziz al-Haqqan

Yes, this is a necessity akhi so do your best not to fall into something haram.
