I recently changed my phone and had to change SIM cards in the process. After that I broke my new phone, so I am looking to switch back to my old phone.
When I tried to change back the SIM cards using the self serve website, I received the following error.
"Sorry, the SIM card number is invalid or already in use. Please try again or order a new SIM card at publicmobile.ca."
Can anyone help me?
Solved! Go to Solution.
Please let me clarify. I have been an existing Public Mobile customer for about a year. I bought a new phone but my old SIM didn't work in the new phone (they were different sizes). I used the Self Serve site to switch SIM cards. I have been using my new phone for about a month now, but I recently broke the phone and I want to go back to my previous phone.
I tried to change the active SIM back to my previous one.
Your old sim card is useless. Once you transferred your account in selfserve to the new sim card, the previously used card was permanently deactivated. You will not be able to simply register it again via selfserve.
You can either order a new sim card, or you can use sim card adapter so the new sim card can fit again in the old phone. These adapters are really cheap. Check the cheap local mobile shops/stalls in shopping areas near you.
I'm assuming you are trying to go from smaller to bigger. you can always try to buy a sim adapter
im sure you can find something cheaper
