juliedeville Been using it for sometime, its the best voip service i ever tried, no call drops or quality issues,all sms and otp works perfectly fine for me. (Used mysudo and hushed previously)
I have two numbers ported to it, linked to same balance 120minutes/month, first number is 5$ every additional number linked to same balance is 2.45$. They support international calling, calling rates are different.
I use their own esim for mobile data, its Plus mobile from Poland roaming in USA and Canada on Rogers, Bell, Telus, AT&T, and T-Mobile, they support only 4g though.
Costs $6.99 / GB + $5.50 / year, data never expires.
Their own cheogram app have integration with native phone app, so you can make and receive calls like you do with a regular number, for checking sms you need to use their app. Last time i checked they said they have plans to give option to make it default sms app, but no eta on it.
