change sim plan but my 20% discount code is not valid

[rose_thyme]

I would like to change my sim plan but my 20% discount code is not valid when I select the plan I want.

@rose_thyme  does the plan you’re choosing already have a discount on it ?  If it does you can not apply a 2nd discount to it.

Hi @rose_thyme

Which plan are you trying to choose? If you select a different plan, does it work?

If you're connected to a VPN, could you try without it activated? 

Thanks

Chris
