I have a Drone Mods GPS tracker. It stopped working last year due to the service provider. I've had it for a few years and really liked it. I tried contacting them with no reply. I got to thinking...what if I got a different sim card from a phone store and replaced original sim card. I'm sure I would have a different number to call and have a monthly fee with the service provider. Will this work and would it work as before using Google maps I presume. I would call the number and then it would send my phone a text with a link. I open link and see map with icon of its position.
