Solution to the error Unable to establish a wireless data connection

On the Samsung Galaxy S6, you may have the following message when trying to connect to the 3G network to send a MMS: Can not establish a wireless data connection. LTE: ESM – 38 EMM – x.

And you can not send or receive MMS.

To fix this problem, simply disable the location of the smartphone (Settings> Connections> Uncheck Position), which can be problematic if you lose it.
