It seems like TTOG used up 500MB of mobile data in a matter of days:

That’s more than 30MB per day! And some days 60MB. That’s crazy. Normal UDP packet forwarders use about 3.5MB of data per day, which means TTOG leaks a lot of unnecessary data to the internet 
I’ve factory reset the gateway and will recharge the sim card with another 500MB and see if this happens again. If it does I’ll have to dive down into the firmware and see what is using all the data.
