I have a Nokia 3310 3g model TA-1022 with firmware 220.127.116.11.00. When I attempt to set up call forwarding to another number it instead sends all calls to voicemail. The SIM is for the UK operator EE.
I know the problem is with the phone and not the handset as I have tried it in a Huawei P Smart and call forwarding works perfectly. If I then put the SIM into the 3310 calls stay forwarded. This cannot be disable from the 3310, I need to put the SIM back into the Huawei.
Please could you let me know if there is a step I am missing or is it a bug with the phone.
