In Spain we have the bad habit of thinking that “whoever pays rules” and this is not always the case . As much as you are a client of a telephone operator, you cannot do what you like with your products or services, but there are a series of conditions and restrictions on the part of the company. If you are a Movistar customer, we are going to review what you are prohibited from doing as a mobile rate customer.
The operator has set 7 guidelines on “Correct use of the services” . Failure to comply with them and making any use other than the above that could cause harm or harm to Movistar or third parties can get you into trouble.

What does Movistar prohibit you as a customer?
One of the first restrictions on the use that you can make with your line is the prohibition of making calls directed to numbers of call redirection services , which imply the concentration or transformation of traffic, as well as calls directed to 908 numbers, of Red Intelligent (special numbers: 0xy, short numbers, m2m numbers, etc.).
Another of the sections to take into account is related to the ownership of the service. The owner of the line may not, in turn, carry out a resale of the service. There can only be a commercial exploitation between the client signing the contract and Movistar itself. You would be breaching the appropriate use if you obtain a direct or indirect economic return from the resale of the service or any of its capacities or functionalities .

The contracted service may not have the purpose of listening or remote surveillance , as well as any connection, regardless of its duration, without the purpose of active communication between individuals.
When contracting a telephone line with Movistar, the SIM card that we will receive is only authorized for use in mobile phones , so you should not use it in other devices, the operator placing special emphasis on inappropriate use in switchboards, SIMBOX or other elements of concentration or transformation of traffic or designed for making massive calls or for traffic rerouting services.
As for the increasingly extinct SMS text messages , the use of the SMS facility in connection with an application or a device that allows mass sending (for example, a modem), or, in In general, sending SMS for any other purpose outside of the contract.
In addition, they also prohibit what other higher regulations already prohibit, so you will not be able to use your telephone line for any use that is contrary to Spanish or European regulations , such as any breach of regulations regarding content, intellectual property, security , privacy, etc
Inappropriate use of roaming
Finally, we are going to focus conscientiously on one of the conditions that should be taken into account, the one that we could probably fail to comply with the most, even without realizing it. When traveling, we have roaming included with Movistar, but we may not be so aware about what is considered the appropriate use of data while roaming .

If inappropriate, abusive or fraudulent use is detected, a surcharge may be applied for traffic carried out in Roaming Zone 1 or EU Zone. What do you consider these uses to be off limits? Well, examples like these:
- Predominant presence and consumption in EU and EEA Roaming by the customer compared to national presence and traffic.
- Long inactivity of SIM cards associated with a majority use in Roaming.
- Acquisition and sequential use of multiple SIMs by the same customer in Roaming.
- The organized resale of Movistar SIM cards.
As can be seen, it is mainly intended that the use of the lines is mainly focused on achieving navigation abroad without demonstrating that we also use a Movistar telephone line in national territory, as well as any trick to continue having free navigation abroad. of our borders beyond the marked limits.
