Great for what it does

I have a SIM card for my “International phone” which is an older iPhone (just in case...). Even though the current version of the app requires iOS 13, thankfully I can still use the older version to keep up to date on my balance and add time as required.

Used to work PERFECTLY, but does not work on the iPhone X or iPhone XS Max on current iOS. Please fix!

Works well. Good help.

Great app to manage OneSimCards sims. Works fine. Needs more account features though, like 1SIM fund, discount packages and use records.
