Qatar's laws are different from other parts of the world, and the French authorities have advised fans to bring two cell phones with them to Qatar to avoid falling into the French Open without realizing it.
The French Information Technology and Freedom Commission (CITF) reminds fans that there are two types of applications on cell phones that are illegal in Qatar, one is an online gambling program and the other is a dating program. If you have either of these applications on your cell phone, it is recommended that you delete them before entering the country as they are illegal under local law and offenders will be sentenced to imprisonment and fined.
However, the best way to do this is to bring two cell phones with you, the one you normally use for your own use and the one you use in Qatar, because when you go to Qatar to watch football, the local regulations require visitors to have two applications uploaded on their phones, one is the World Cup Official Formula, which is used for ticket detection when entering the stadium, and the other is the new Crown Pneumonia Epidemic Monitoring Program.
