The SMS (Messaging) app is missing on my Microsoft Lumia 535 dual-SIM with Windows 10 Mobile TP build 10536.1004 after resetting. How can I get it back?
I noticed the same thing, but you actually can just install it from the store. Just open this link in your phones browser:
This is a known issue. Microsoft have acknowledged it and provided a service-side fix. You'll have to hard reset your phone again to get the app back.

I added the correct link as the one by Thomas doesn`t seem to work!
The link and download only worked once I'd switched location off and set region as United States. Probably have to set storage to download apps to phone as well.
