How do enable sms delivery confirmation and call history on windows mobile 10 ?
I've just bought two phones :
- a Microsoft Lumia 640 AT&T (RM-1073) is unlocked.
- a Microsoft Lumia 640XL AT&T (RM-1063) is unlocked.
I made the Windows Phone 8.1 updates to the latest version of Windows Mobile 10: 15063.674. On these 2 phones, I do not have access to the following options:
- Activation of the SMS and MMS delivery confirmation
- The history of the received and issued calls that remains hopelessly blank.
I also already have a Microsoft Lumia 640 XL (RM_1072) bought in France unbranded, on the latter on Windows 10 Mobile last update these 2 options work fine.
How to do with the 2 mobiles that I intend to offer my parents to replace their Lumia 520 which they also work fine with these 2 options?
Thanks for your help
