Hi.
So arrived Sunday and popped Telsim $45/70Gb sim into my (and my wife’s) iPhone Monday morning.
Activated fine and working perfectly as you’d expect for Aussie.
I can call any of my NZ people just fine (+642xxxxxx) but I cannot text them at all.
Been onto Telsim support and they have checked with Telstra, and all are pushing back saying there must be restrictions on (ALL) my NZ numbers at the NZ user or Telco end, which I simply cannot believe.
We’ve tried 00612 prefix, a variation that had 11 in their somewhere too, but nothing seems to make it happen.
I’ve gone through and removed my NZ number from my own contact and also under settings > mobile > my number and only the Aussie one is there now.

Anyone had any similar issues and solved them?

Can you confirm that you are using the +642xxxxxxxx format when texting your nz contacts?

If you can't laugh at yourself then you probably shouldn't laugh at others.

yep… I can try to txt and it fails, and I can make a call to them on the same number and it works (from mine & my wife’s phone).

@fritzman You need to only deal with the A party (sending) network not B party as you can't trace something backwards if the SMS is not arriving

The only format you should be using is +642xxxxxxx and nothing else

Telsim support is telling you porkies and just trying to fob you off!

Thanks.. kinda what I thought, but not qualified to press too hard.
I still believe that it’s something to do with the way the back-end of the sim has been set up., The way I see it, if I can phone the number and talk to the destination, there’s nothing wrong with the number in contacts.

I couldn’t help wondering whether my phones are trying to send an sms using something other than the newly introduced Aussie number. I removed the 2degrees sim while the plane was taxiing out of Auckland, so hopefully the network reset cleaned out all the memory of that.

I’ll keep the pressure on Telsim support then.
Thanks.

Not that it helps, but a family member had a similar issue a few months back using Everyday Mobile which also uses Telstra Wholesale - Oddly wasn't to all numbers, just some.

I could call her fine and she couldn receive my texts, but SMS's to me just failed, we ended up just moving to my other number to get around it as also got a similar runaround from the support who said nothing was wrong.

Any comments made are my personal views and does not represent those of my employer

Thanks for all the suggestions and advice..

I think that as it only cost us AU$15 each for 70Gb each plus unlimited calls AU & NZ, we needn’t be too concerned about not being able to txt kiwis.. we’ll just have to call them instead lol.

Random question (and I could be well off the mark).

You said you both used iphones. Is it trying to imessage them instead of SMS? I'm wondering if the registration SMS to the UK (I think) to allow this failed, leading to this cascade...

Great thought.. turned iMessage off and tried to send a txt to an NZ number.. immediate fail again, so I guess it’s not that. I could turn it off, do a network reset, restart the phone and test, but I’m not sure it would make a difference.
