The Replacement SIM activation process is insane

So for various reasons I've had to activate 3 replacement SIMs in the last two months. Every time, the process to actually activate it is nonsensical. You put the unactivated SIM in your phone, open the app and do Activate Replacement SIM. So far so good. But then it texts you to confirm the phone number! It's texting you ON THE NUMBER YOU'RE TRYING TO ACTIVATE. I'm sure there are some situations where someone is getting a replacement SIM but still has a working phone, but those have to be the minority of the time. (If your SIM is working, why are you replacing it?) And the only way around it is to contact you support and sit in the queue to get an agent to activate it manually. It's incredibly frustrating. And all that would be required to get around it would be allowing users to set up a backup phone number in advance so that number could be texted instead!

Anyway, rant over, just fix it please Mint. I've spent so much time waiting for Mint support.
