Blog - Important News About X-SIM Adapters

Dear X-SIM Adapter Users,

Apple did fix the bug on activation server which was used for X-SIM Adapter functioning.

Our coder will check if any other bug can be found and if/when we can make update.

In the meanwhile advise customers with the adapter not to make any firmware update.

Next time iPhone will contact Apple Activation Server adapter will become useless.


For now you can update firmware to some old one - go to this link:

Firmware v4.4 working with some SIM carriers from some Carriers - please send us feedback from your country

Update tool

Upgrade Manual 


and see if adapter can be used on new iOS with your local carrier.

We are doing our best to provide you new updates which will be FREE for all X-SIM Adapter users (require update dongle).
