Pay as you go call forwarding not working - Connection problem or invalid MMI code

[ekopay]

Hello, I have a pay as you go sim and I want to be able to forward calls to a number when I need it but I get

'Connection problem or invalid MMI code' error message when I try to enable.

MMI codes I tried:
**21*{UK telephone number}#  ---> I get the error, I tried with another O2 number and a LycaMobile number with samew results.
##21# --> this works, I get a positive message for disabling all forwarding settings
*#21# --> this works as well, I get response when checking current settings.

 I tried calling support service and also going to O2 shop without receiving any relevant help and just telling me to try changing my pay as you go with a contract which I don't want.

Any help? My other option is to change provider. Thanks

o2 PAYG doesn't support call forwarding so you are going to be best moving to a new network

Do check other providers. Most of them do not support call forwarding on PAYG. This is because someone who has phoned up and whose call is forwarded can be cut off if the phone credit runs out as you are paying for the forwarding

It's the only way.

I'm not aware of any PAYG networks that allow it.
