I was told before I purchased a T-Mobile plan that my GSM 80/900/1800/1900 MHz device would work. Was this just a sales pitch to get me to purchase the service? I see the disclamer that on 1700/2100 will work on teh T-Moible network. Is this true or will my device work?
It will work... Just no 3G/4G
Thanks tdbits. I have not gotten it to work yet, but still playing with it. It's actaully a GPS tracker that you control via SMS commands. GPS is working, just not getting the SMS responses back. I'll keep playing with it.
you need to setup your SMS protocols.
Internet and Picture Messaging (WAP, MMS)
Short Message Service (SMS)
That device will work on 2G like tidbits mentioned. I am not familiar with the device you are referring to but the settings that tidbits also referred to is a great starting place.
Thanks Andrew!! The device is a TK110 GPS tracker. It only has commands to set the "center" which is called "Terminal Setting", the APN and the server ip address and port. I will set the center and APN and let you know how it goes ;-)
It's working now. I went to a T-Mobile store to try the SIM in a phone, and come to find out they had SMS blocked for some reason. As soon as they enabled it, it started working. It worked great the first night, but now when I send it a message, I don't get a SMS reply for about an hour. Don't know if it's a setting on the GPS or not. Going to set it back to factory defaults and see if that fixes it.
I don't think the GPS is the problem. I put the SIM in an unlocked phone. The SMS is very speratic sending SMS messages. It fails to send about half the time. It recieves evertime. Would this be a coverage problem or some other problem? I made sure the center number was set correctly. Actually I didn't have to set this, the phone found it on it's own.
you can help me some thing GSM 80/900/1800/1900 MHz device would work thanh you MLEBER
