I ported my 021 number to Telecom (NZ) nearly 12 months ago and thsi has been working fine. Over the weekend I noticed that no texts were being sent or received so I called Telecom. After I eventually (4 calls later!) found someone who could give me any sensible help they taled me through 'crashing' then re-setting my phone, then they tried removing my number from the network and re-adding it. They said that the next step was to take the phone to a Telecom dealer to try porting my number to anothe phone.
This I did (after much persuasion and many more calls to Telecom). They moved my number to other phones and back to my phone but always the same issue. No texts to or from the pone with that 021 number.
I can always talk on the phones without a problem.
Has anyone else had this problem, or know the solution? They are still trying to fix it.
