permanently lost SIM abroad

[Sobo1]

Hello. Before corona I moved into different country and forgot to use my SIM. It's been more than a year now since I last used it so it is permanently lost now. 
I need that number because it is linked to one of my bank accounts and I can't change it without it. Can't travel to buy a new one. What should I do?

Is it on contract or PAYG?

PAYG? I guess? I lived there shortly, so I bought the sim card somewhere and the go and added credit weekly so.. without contract.

@Sobo1 : You've lost the use of that PAYG SIM & no. completely after such a long time of non-use.

EE PAYG SIMs are deactivated after 6 months of non-use. You then had a further 3 months to call EE to reactivate it before it is lost completely.

You needed to make a chargeable action like making a chargeable call or text, topping up or buying a Pack or Add-on, not just using your mins, texts or data from your pack.

It has been already more than a year now since I last use it, for sure. Maybe even two years now. But thank you. It seems I have to terminate my bank account and create a new one.

Surely your bank will change your contact mobile number without changing accounts, after suitable security checks.
