Verify it worked by checking that the phone number at the top of the 'More' profile page (under your picture) has changed to the new one.Viber will send the confirmation code to the new SIM2 number.(Actually it's desirable to prevent Viber spamming your entire contact book) Viber will attempt to message all your contacts but fail with 'No Service'. Type in the new phone number (from SIM2) and press Continue.Go into Settings > Account > Change phone number > New phone number > Continue > Continue (to prompt about spamming your contacts with your new number) Viber will not notify you it's offline (oh no, proper notification would be too easy.), it will appear as if it's online, except when you try to send a message it will just get silently delayed, or when you try to make a call you get a 'No Service' dialog (but it won't say which SIM, and even if you do have service on SIM2 and SIM2 is enabled as default).

While you are in this in-between state, you will not be able to receive any calls or messages with Viber - but neither Viber nor Android won't actually tell you 'No network on SIM1'.

But SIM1 is disconnected and doesn't need roaming all your data is now coming via SIM2. Apparently Viber needs to see old SIM1 as well, to verify it corresponds to your account, before it will allow changing phone number.Set 'default SIM for mobile data' to SIM2.

In Android > Wifi & Internet > SIM & network, Enable both SIM1 and SIM2.
