Invalid SIM card Number

jadonlu710 — Sun, 31 May 2026 14:46:18 GMT

I wanna open an account and try to active a physical SIM card which was used by my MOM before. She just switched the physical SIM to eSIM today. However, during my new account activation, the error "Invalid SIM card Number, plz try again." was showing.

SIM card is one time used. If it was used by your mom before, it cannot be reused for a new account

you have to buy a new one. Buy a new Public Mobile sim from Telus or Koodo or Mobile Kilink or Amazon

Hi @jadonlu710

Sadly, once a SIM card with Public Mobile has been used, it's no longer valid with any other account or plans.

Here is how you can get a new one.

To get a new SIM card the fastest routes are these.

https://www.publicmobile.ca/en/bc/pick-up-SIM - Find a local store in your area.

Amazon - Here you can get it cheaper and maybe a few days wait $9.99

Or find a Mobile Klinik near you. https://mobileklinik.ca/stores/

hi @jadonlu710

you cannot reuse an already used sim card.

so, you need to buy one. Buy it from a Telus , Koodo or Mobile Klink store for $10

Can my Mom still change back to this physical SIM or not, even the same phone number?

Is it possible my MOM would use this SIM card again if she wanna physical card for the same phone number?

Or is my Mom's physical SIM card completely useless now?

You can order one from Canadian Cell Supplies for $5 and once you have the new SIM. Login to her account then to Account tab-Change Your SIM Card to transfer her account to the new SIM…including her number.
