How to switch mobile providers?
If for some reason, you have intended to stay for a longer period in Switzerland, you would want to ensure that you are on the best mobile network. A convenient way to keep the same number while switching to a network provider of your choice is also available, known as porting. The process of porting is pretty simple, and most of the mobile networks offer English speaking Customer service representatives to avoid the language barrier.
Considering there are so many network providers, this has led to providers competing with each other on the basis of providing the best connectivity solutions. It won’t be hard to find exactly what you are looking for.
