Re: Still horrible customer service

Just back from Overseas and used Covermore Global Sim...very difficult to make work. I inserted into my iphone7 plus which has Telstra Account. Coming back to Australia...could not get Data. Put my Telstra Sim in my wife phone...data worked...pot my wifes Optus SIM in my Telstra phone and it worked. Telstra Shop no real help, ot online Telstra no real help. Apple guy on line got me to Factory Reset iphone wholst downloading all mt stuff to itunes. Did that and data worked on factory reset. However when I restored with my stuff....data did not worl. So factory Reset again and added Apps separatly. Now all good. My understanding is some Policy of an overseas Telco has got on the Iphone and Telstra cannot override. However it seems ok with Optus. My recommendation is do not touch Covermore Global Sim...and just use Telstra $10.00 a day roaming.

Was this helpful?

  • Yes it was, thank you
  • No, I still need help

Re: Still horrible customer service

Yeah those global SIM's have a habit of installing a carrier profile onto the device that can be difficult to remove

There are a few other threads to have potential solutions as well:

There's more but for the life of me I can't find them

 

EDIT: here's another one https://crowdsupport.telstra.com.au/t5/Apple-iPhone-7-7-Plus/Can-t-access-mobile-data-after-holiday-...

 

There was one more that had two different methods that people have had success with (which was the one I was ultimately looking for). I bet i'll stumble across it when im not looking for it
