Open letter to Apple available now.

We have things to say about Apple and the App Store. Michaël Nass, the founder of FMobile and president of the Groupe MINASTE non-profit organisation operating FMobile, wrote an email to Tim Cook, CEO of Apple, Inc. and decided to make this email public. Read it here: raccourcis.ios.free.fr/fmobile/letter.html.

FMobile 5 NÉOn 5G

The all new FMobile, with its brand new NÉOn architecture, and next-gen FMNetwork engine, made for iOS 14, 5G and eSIM. FMobile breaks the boundaries of national roaming on your mobile phone, and allows you to enjoy a much faster cellular connection when your carrier has national roaming agreements. It also allows you to manage your international roaming, coverage maps and speed tests in one app. Its complete unique core technology is accessible for private customers through the Apple Shortcuts app. Over 200 territories and 700 carriers are supported. And best of all, the app is completely free!

Feature 01

Unique powerful technology

FMobile uses a technology that took multiple months of research and developement to achieve the best-in-class no-jailbreak cellular connection management tool. No other app is even coming close to us!

Feature 02

Made for iOS 14

But also iOS 13, down to iOS 9. FMobile uses the most advanced technologies available to deliver a complete, but yet easy-to-use app. FMobile 5 has been designed for iOS 14 with iOS 13-12 backward compatibility, allowing seemless constant background execution but keeping its very low battery consumption.

Feature 03

Get rid of national roaming

National roaming can be great to help a fast network expansion. However, when these deals ends up slowing down your Internet speed, you should have the choice not to roam. Most carriers don't give you this option, that's why FMobile is here to help you. It helps you with any 2G/3G/H+/4G LTE, and now 5G type of national roaming.

Feature 04

A worldwide coverage map

Thanks to its power, FMobile 5 now has a brand new worldwide coverage map. All carriers are supported, and you can contribute to this worldwide map no matter if you're walking in town or traveling aboard on another network. Of course, by default, FMobile will not collect any data. Coverage map contributions are anonymous and based on free-will.

Feature 05

Highly evolutive

FMobile 5 has now a brand new way to manage carriers. FMobile 1.X had some carriers included ready for auto-setup. It was not that great because an app update was required to update the carrier settings. On FMobile 5, with the brand new FMNetwork engine, all carrier configurations and update are coming through Internet, which allows an evolutive platform, and you don't have to worry about anything, the entire process is automatic.

Feature 06

Say no to roaming costs

FMobile 5 is now capable to automatically, almost instantly switch off your cellular data if you happen to use them aboard in a country that is not included in your cellular data plan. No feature of FMobile is guaranteed, so you are still responsible for your data usage aboard, but it is always appreciated to know that a help tool is available and likely to be triggered. It should reduce a lot of your unwanted roaming costs.
