Description
OneSim VoIP provides OneSimCard customers with an even less expensive way to make and receive international calls on their iPhone mobile phones or iPads. To use OneSim VoIP, users must have a good quality Wi-Fi, 3G, 4G or LTE Internet connection and a VoIP-enabled Personal Extra Number (PEN) activated with OneSimCard. When making an outgoing call, OneSimCard users can select the way the call will be made – either through the OneSimCard international SIM card or OneSimCard VoIP network. Calls made over the VoIP network are generally much less expensive than OneSimCard’s standard international roaming rates. Incoming calls made to the PEN will be received through low-cost VoIP if the OneSimCard phone and OneSim VoIP app are registered on the Internet. Otherwise, the call will be sent the usual way to the phone through the international SIM card.
The newer version 2 of the app adds the texting feature and allows the sending and receiving texts (SMS) to and from US and Canada mobile phones over Wi-Fi or mobile data at much lower rates than regular SMS sent and received over the roaming network.
The app does not require having a OneSimCard SIM installed in the phone, but it does require having a OneSimCard account and a VOIP and SMS enabled PEN.
Initial settings for the app are available in the “My SIM Cards” menu of the OneSimCard online account. When in the My SIM Cards menu, select the SIM (if there are more than one on your account) and then click on the Create VoIP Account link. This will create a OneSimCard VoIP account and provide you with a link with Settings information for your phone.
Important: Connection quality of the calls made using OneSim VoIP option over the Internet will only be as good as the quality of the Internet connection. Please be advised that in many cases this kind of connection quality is inferior to the connection quality made through the OneSimCard international SIM card roaming network.

Good business thank you for your business and everything

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).

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.

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· 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.

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
