SIM issue on LIVE 540 error 1001

Morning everyone.
Got a quick question - if TomTom are experiencing server issues for Live services, would the mobility.sim file look like this :

[GPRS]
MNC=
ICCID=
IMSI=
IMEI=
Model=

I personally don't think so, but then I'm no expert in this. I would have presumed that there would be something there (on the device) to handshake with the servers, and the servers to say a big fat "NO" when trying to access the services.

This looks more like the actual simcard is isn't working.

Could anyone enlighten me ? Confused

You could try removing/reinserting the card. (It's under the C € part of the underside sticker)

Just done that, Franb - had visions of having to dismantle the TomTom ! Thanks for the info Smile

Still no difference in service, however. The simcard looked fine, with no damage or wear and tear to the sim itself.

I'll wait to see what "wisdom" Support come back with.

Go to Change Preferences/ Version Information/ Network and what does that screen give you in way of information - Mike

Hi Mike and Paul Smile

Error message of "There is something wrong with your sim - error 1001"

All of the entries there on the connection status screen are blank. All the software is up to date, but I did the normal rigamarole of cleanflash, restore an older windows backup, reinstall the software from scratch - I don't mind the time it's taken, TomTom have convinced me over the years that this is "therapeutic" ;)

I only ask because this has happend before, but only after the rollercoaster ride that was upgrading from 8 to 9.

Apart from that, it picks up the GPS fine, and everything else works as it should.

Who needs Live anyway ! Laughing Out Loud

It looks like the key is to run the battery right down until it wont switch on again and then leave it overnight. You don't need to charge for 12 hours as other members switched on after 30 minutes charge.

I had the 1001 SIM card error again on Tuesday after I started up the unit at home (I had previously experienced it a few weeks before and did the full battery drain business back then which I now believe to be unnecessary).

My solution this time was much simpler and does not involve any time consuming battery draining.

This works as follows:-

1. Do a soft reboot on the unit in the place where you first have the 1001 SIM card error by holding down the On/Off key for 15 seconds or so until it reboots and keep holding down the On/Off key until you reach the black and white hardware/BIOS reporting screen.

2. At the black and white screen about the processor number, amount of memory etc release the On/Off button. Wait a couple of seconds then press the On/Off button again quickly eg for less than a second. The unit now turns is now fully turned off with no processor activity or battery drain going on.

3. Drive to somewhere else that you know is definitely served by a different mobile phone mast from the one where you had the 1001 SIM errror and couldn't access the Live services.

4. Turn on the unit by pressing the on/off key for a normal half second or so.

5. The unit starts up with the TomTom symbol and drum roll sound as it is from a previous soft reboot.

6. The unit now logs on to Live services normally and you can continue using them until for no good reason it may well happen again and you get another 1001 SIM card error. If that happens repeat steps 1 to 5 above.

The problem seems to be caused by something happening during a log on to the TomTom Live servers at a particular transmitter site that causes transitory data to be stored by those servers that gets your SIM rejected by the Live servers at that transmitter repeatedly until it has logged on them from a different Vodafone transmitter mast site (at which point it can then also access the Live servers at the problem mast location again). Doing a soft reboot and shutting off the unit and then restarting it when you are in an area covered by a different mobile phone mast seems to cure the problem. The soft reboot and subsequent full power off procedure may be unnecessary and next time I will just try swapping my current mast location after powering off the unit without bothering with the soft reset procedure this and see if that works too.

I reckon the only permanent fix to this issue may be to return the unit to TomTom for SIM card replacement or better still to have TomTom send anyone with an x40 series unit one of the new x50 series SIM cards that do not seem to suffer from the periodic error 1001 errors with Navcore 9.058 if it is easy to do your own SIM card replacement?

After reading the earlier posts in this thread I took off the sticker on the bottom of my 940 and prized out the rubber plug over the SIM card slot but I don't see how you can actually replace the SIM card itself through this slot without a special long pair of tweezers?

There is of course also access to the SIM card via the known procedure to fully disassemble the entire unit but I don't fancy doing this until my battery actually needs replacing. Although after 18 months I did have poor battery life after a recent few full charge/discharge cycles using the PC docking charger I found that the normal battery life was restored as the battery memory effect caused by numerous short charges from a non discharged state by the car charger was eliminated.

Hey all, thanks for the replies. I've run the unit right down, then used a mains adapter to charge up a bit, but still the same.

Not planning on driving for a little while, but I'll certainly try your method Wacky Smile

Cheers again, everyone !
