Do you know that? You are a giant event, want to call someone and don’t come through simply? Then an SMS, writes better than on major events such as the Oktoberfest, a mega concert or the ILO have the networks of the mobile operators to do much right, and are therefore often hopelessly overloaded.
You should write therefore everywhere where the bear dances right, rather a SMS to his friends and family as to call them, advises the information centre mobile (IZMF).
The reason for this is that the amount of data in a text message is significantly smaller than the amount of data on a call. An SMS has therefore significantly better opportunities, to get through the blocked power supply to the receiver.
And here’s a tip from abbreviationfinder: If you can make a call at a large event nor send SMS, you should change even tentatively of the UMTS network in the GSM network. Your Internet is then quite slow, but probably also less slow networks are overloaded. So you come out with your smartphone from UMTS, you have to disable the 3 g connections in the settings.
