A GPS tracker has worked on a PAYG EE SIM card for over two years. The other day it suddenly stopped sending GPRS data. I can text the device and read and change settings. I can phone it, hang up and it returns a text of correct GPS location coordinates and a link to Google maps.
I can command it to turn on either SMS or GPRS data, and it returns "ok", but when I read its settings by text it shows GPRS remains stubbornly off. Of course,. with GPRS off it cannot send live positional updates to the tracking server.
I have plenty of EE credit, calls, data and text wise, but topped up as a precaution yesterday, but nothing changed. Is there any data limit that may have been exceeded, although GPRS in this scenario is very very frugal?
Is this setting held on the SIM card from EE, or in the tracker device itself? Has anything occured to possibly effect 2G GPRS "stuff", or have there been any sudden changes in APN settings?
Can a SIM "wear out" in a tracker or become corrupt? The device shuts down by he vehicle cutting power to the circuit its on after three hours, so it is rebooted on average twice daily.
Thanks for any advice, I wiped the data to the device's factory setting and input the tracking and APN data afresh, but GPRS remains off, so no live updates are forthcoming.
I have a different make of tracker also on an EE PAYG SIM and with the same GPS tracker map people, and that remains outputting GPRS with live updates just fine, and has been so doing for over 2 years.
