So far, not so good
Only been using it in UAE, maybe it has to do with the network here, but having a lot of trouble. The right service was trying to call me at at the airport, had all kinds of trouble taking their calls; no, I’m in a hotel room and I can’t load anything related to my account, such as checking how much data I have left, can’t even go to the side (OneSIM) e-store

Calls and messages don’t always go through
I’ve had several friends tell me they tried calling me but, after a couple of rings, they lost the connection. Meanwhile, I heard no ring and did not get a missed call notice.
Text messages also don’t always go through in either direction.

Worst VoIP app I’ve ever used
This app is a complete nightmare to use.The user interface is very complicated, when I allowed to contacts and call a number it called another number not related to the first one.The API requests and responses of this app show plane-text passwords and plane-text user IDs. The communication is unencrypted… Furthermore, I didn’t use the app for one week and 1Sim blocked my account. Now I have to pay more to use my account which has funds. Worst experience I ever at. Never using it again.

Cannot receive calls
Due to an iOS update you cannot receive a call unless you have the app open in the foreground. Not useful to receive call when in the background. Only useful for outgoing calls
Great app. Saves money
Have been using it for long time
Works somehow but mot enough help.
You should let people know that with some wifi signals it won’t log in or make any calls, on those cases a data connection is required. Need better customer support, too slow and difficult to make questions.
Great app
The updated SIM VOIP app works well.
Big improvements
This app was horrible and barely worked about a year ago. I recently tried it again and it has been working great for texting and calling. Considering cancelling my other service after I test it some more and make sure it’s reliable.
Horrible
It doesn’t work. System is unintuitive and poorly designed. Good luck getting tech support or customer service. There’s nothing like being in a foreign country and not being able to verify your card.
Full of bugs
Poorly designed app shows the wrong names on text and calls does not link properly with Contacts release prematurely should have been tested before pushing it to the App Store. Been a customer for three years not compatible load banks as they claim if you need a real number for verification we need one tie to your Social Security number with a real eSIM provider

Works as stated but 1 problem…
The problem I am having with this app is when menus say Press 1 for …. When I press 1 it is not recognized by the answering system. Pressing 2 or 3 seems to work but on several outgoing calls the 1 prompt doesn’t work. App developers, can you fix this? Thank you.
Truly terrible support
I had a problem not reciving SMS on the APP, everything else was OK. I contacted them via the website and they did not pick up, they told me to send the message. The return message said I had to DELETE the ACCOUY! I contacted again and they told me to delete and reinstall the APP , which is easy enough but they did not check if the issue was repaired and closed the chat abruptly!! The app is working now but not thanks to them!!

Will not work / install properly on my iPhone (iPhone 13 pro iOS 16.4.1)
Installed on my iPad calling feature not working and if they are the signal is very poor. Brought up the problems to the “technical “ support team. They are very committed but can not give any solutions. Trying to get a refund no response.

Dreadful app
I would give it 0 stars if I could. Customer support is non existent and will simply blame your ISP or your phone manufacturer rather than attempt to even help solve the problem. Don’t waste your time
Waste of Time
This is a dire application. Looks like something from the 90’s and as slow as something from the 80’s. I also can not enter my account to sign in any more. Terrible. I don’t know how much time I have wasted trying to get this thing to work.
Mr Savjani
Dowloaded on 3 different IPhone’s, does not seem to work. Please help
Can’t log in
Won’t recognize my OneSim card number - either number. Can’t log in. Account active through OneSimCard online.
App has worked great until iOS 10
This app has worked perfectly up until iOS released now when using the app on Bluetooth there is a continuous drop in and out creating a clicking chop to the call. Please address this issue...
Crashing
This version keeps crashing in my iPhone
Crashes on iPhone 6+, iOS 8.3
Used to work on iOS 8.2
