Adding a 2nd plan when you've switched your old number to your new plan and now old sim won't receive your one-time passcode

Hi 

I’ve just taken out a 2nd plan. I’ve just switched to Tesco number to iD Mobile thinking my Tesco sim would then work with my new contract - it is connecting to the internet but not data, and send or receive calls or texts. I went to register the 2nd plan on my app to see if I could fix it this way, but it’s trying to text a one-time passcode which obviously won’t work as the phone can’t receive calls or texts. So, I went to Curry’s today to get an ID Sim, but can’t register it to my app still because I can’t add the 2nd plan to my app. I’m completely stuck with how to resolve this, please help. 

Thank you.

Hi Anika. Thanks for your reply. In the meantime I managed to speak to a colleague of yours, they talked me through these steps but I got a 'Oops there's a problem message'. I have since emailed my ID and I'm now in a queue for my SIM to be activated within the next 48 hours. I am now 8 days into my contract and haven't been able to use my phone, 4 phone calls down and 1 trip to the Curry's store. I hadn't realised it would be this difficult, time consuming or stressful setting up a 2nd plan  - I've also had a colleague of yours attempt to sell me an upgrade in this time! What a frustrating experience.
