Asks for tello number to send one time passcode but then says enter valid number . Can’t even use my email id to login.

App is great sound quality needs improvement. The fact that I can call US numbers when out of the country without being charged international fees is amazing.

This provider excels compared to all others in terms of price and flexibility and is a good choice! The only issue is when making international calls, the recipient is always presented with the wrong caller ID probably because the call is re-routed causing the caller ID to get lost/changed. This causes recipients to mistakenly assume the call is spam and not pick up or reject the call. This needs to be fixed! International roaming is great but the rates are not competitive. It would also be good to introduce texting via the app, and brush up a little on its overall visual appearance (e.g. dark mode).

The app does not anything when making any of the selections under “My Account”. Also, nothing comes up when selecting “Plans” and “International Calling”. This is on version 4.5.62, a very recent update to the app.
