Prepaid Sim doesnt register at network
I bought a Prepaid Simcard + 10 USD to fill it up (not knowing I would need 30 for the smallest plan), as we are traveling in the US only for a month. Setup worked smoothly, 10 USD was on the account, but i never received a PIN code or anything.
Went to a AT&T store in Sheldon, CT, where I bought 20 USD to fill it up to 30. Still didnt work. Shop then used two other SIMcards, to try again, but didnt work. Alsl did not work in their phones...
I assume my account is blocked, but Customer Service (shop called hotline 5 times ...) couldnt help because I dont have a PIN number for the account
So anyone any idea how to reset all account details? (my phone is not the problem, it does work with other skm cards)... All I have is the SIM card numbers and maybe my phone number (ist shows up in the sim card properties, but never connected...)
Thank you so much for help!
