Hi @Vezirov, you need to configure your new IPhone. Here are the indications:
To enter the APN go to Settings> Cellular> Cellular Data Network.
Fill in the "APN mobile data" field with the address "web.ho-mobile.it" and the "APN Personal Hotspot" field with the address "Internet.ho-mobile.it"
Make sure that no other characters appear in the APN fields (Ex: http: \\ or spaces) and that the Internet is written with a capital 'I'.
Ignore the parameters for the MMS configuration, the service is not available on the Ho network.
In addition, we advise you not to copy and paste the text message but to proceed manually, the phone copies the APN address incorrectly. Reboot the device.
We remain available. Good evening.
