4G Tracker.

[JockandRita]

Any guidance or pointers would be much appreciated please.

1. We have changed from a 2G tracker to a 4G tracker, and until September 2025, it was working a treat, tracking us all the way to Aabenraa in Denmark. As we made our way back towards Calais, it still had us logged as being at Aabenraa. Once back in the UK, it worked a treat again.

2. When heading down to Spain, it tracked us to Newhaven Ferry terminal on 30th December gone. It never tracked us again, (despite calls and messages sent), until on the way back, when we entered the non toll section of the A13 at Rouen on the 26th of March, whereupon it tracked us right up to Dieppe, across the Channel on the 27th, and then all the way back home on the 28th.
I've just sent it a text message from a +44 number, and got an instant reply with a map showing it's location.

I have checked that the sim card is on 4G roaming, and with international calls enabled. The tracker itself is 4G. I really don't know what else I can do, to ensure it performs correctly wherever it is in Europe.

Any ideas please?

TIA,

Jock.

Have you contacted the SIM provider? Is it possible to reset the device somehow?
If you can get the SIM out try to do a "Sim clean" by wiping it with some clean cloth or contact cleaner.
This may help, we have SIM PDA's at work and they can be awful to connect to the delivery system we use. And this works and also removing the battery for 10 seconds..

Re the sim card, not yet, but I'll give it a try thanks. TBH, I don't know why I didn't try that myself, as had it been a problem with a mobile phone, that's exactly what I would have done.

I have tried the reset, and resent (and received by return), all the message codes to set it up again. I don't get how it never tracked us from Newhaven to Benidorm and back, yet once at Rouen on the retun leg, it tracked us from there to home, without any interferance from me to either the unit or the sim card. It's an ASDA PAYG sim which uses the Vodafone network.

Cheers,

Jock.
