★★★★★ 5 star music world global unerground · Mar 25, 2021

Good business thank you for your business and everything

★★★★★ Phil Laffy · Aug 24, 2023

Works great for low cost international calls when traveling

★★★★★ Ground Zero · Jun 15, 2023

Tho I agree, if working fine, don't try to do so much update, but this app update is long overdue. Latest update have simple, better looking interfaces, background running is ok, seems like everything work better.

★★★★☆ Chris Davis · Jun 14, 2017

I use OneSimCard for travel when my primary phone can't be used. Using VOIP costs less than making calls on the wireless carrier. The only thing I don't like about this app is it will only ring on vibrate.

★★★★★ A Google user · Jan 4, 2018

I got onesimcard for travel, and with this app I use the same phone number dirt cheap with Wi-Fi & still stay in touch when I don't. Used it in 6 countries on 3 continents. Very convenient & efficient. Also comes in handy in buildings where mobile service is bad; it works wherever Wi-Fi does, and I can easily call any phone number (unlike other VOIP apps).

★☆☆☆☆ A Google User · Sep 19, 2012

Receiving call is expensive to the calling to sim card. The voip use Wi-Fi if you have Wi-Fi available you are better go Skype or Obi.

★☆☆☆☆ khaled A. · Jun 4, 2021

Very poor customer servive no one can help. Multiple crashes. Poor quality. Don't use it

★☆☆☆☆ Emmy Marcel · Oct 12, 2021

Can't work up to standard, it all about money money money. I spent a lot yet no result. App crashes, even SIM cards crashes, this is crazy. How do you cope with US based communication companies? Very annoying

Trust & Safety: The app requests a broad set of permissions, including location, network state, notifications, internet, microphone, camera, and contacts, along with boot and foreground service permissions. This aligns with VoIP/SMS functionality but warrants a privacy review and minimization to protect user data.
