Tried two of these units. Neither would charge properly even after manufacturer mailed new charging cords. Waste of time.
[DATA ONLY] Ablegrid® AT&T IoT SIM Card for GPS Tracker or Any IOT Devices LTE-M 4G
if you have difficulty to use this sim card, pls let us know, we are here to solve the issue.
please make sure, your device must be certified by AT&T, otherwise, it will be disconnected by ATT anytime automatically. again, this is IOT sim card, NOT regular ATT voice/Data sim card. thanks
This has to be the worst tracker on the market.
It worked absolutely perfectly - for around 3 weeks.
Then the tracker died.
The SIM still worked perfectly, so I used that in another tracker, which worked perfectly.
Then the SIM died too - no reason at all.
I have bought another SIM, which I am waiting to arrive, which will then have the remaining credit transferred.
However, I'm not holding my breath that this will work.
Overall, one of the worst products I've ever bought.
And the technical support is even worse than the product.
The sole positive thing I can say about the technical support is that they answer promptly.
However, they don't read what is sent to them - and appear to just select a response that they feel like sending.
Such as "charge the tracker".
"remove the SIM and put it back again".
"Put the tracker where it has access to the network".
Crap like that.
What a waste of time this company is - worst I've ever dealt with.
According to your description, your tracker does not certified from ATT, ATT bans the device if their system find out the device uses ATT IoT sim cards , which is not certified. so the device will works a while and dead for ever. all certified trackers use unique imei patterns

IoT sim card are not regular sim cards, pls make sure you understand it before buying , only certified ATT device can use ATT IoT sim cards , don't waste time , and also, we have nothing to do with the sim card network connectivity , we are not ATT, we are a dealer only.
IoT signal coverage is not covered in all areas in the USA by ATT, but AT&T has the best Cat-M signal in the USA. we supply massive sim cards for the car dealerships in USA , our trackers are used in lots of big name customers such as NASA. it is the same thing you can not use the cellphone in the desert, or sometime your cellphone loses the signal. we hope you can find the better service providers. thanks for your business.
