cannot update sim card

[bbbb2]

When I try to update my sim card I get the a message saying the old SIM card is not the number associated with my phone.  I've tried several times with different browsers and am sure I am inputting the number correctly.  How can this be resolved?

Hello @bbbb2

You should be able to update your sim card without a problem through Fido.ca.

At the same time, the number of your old sim card is required in order to do the sim card change.
