Totally not an issue!
I've got one of these, the device itself communicates with the server over GSM.
It's the software running on the server end which may have an issue, BUT there is a very good Open Source Software server which runs on everything inlcuding a Raspberry Pi.
This is only an issue if using some closed source server software from China.
On the other hand these and their clones are great units, which can do a lot more than just vehicle location....
Biting the hand that feeds IT
