UCM/4G upgrade problem

[Ian]

I had a look at Laser systems web and it the module appears to be 3G Will it work with 4G?
Comfort GSM Module version 4 (3G)

Laser should have UCM/4G. I believe they may not have updated their product list. I suggest that you check with them

Thank you.

Is it possible just to buy the piggy back board which holds the sim?

Yes there is a part number GSM/4G. But the ucm/gsm base board should have firmware version 7. You will need to upgrade to the laest firmware which will work for 3G and 4G

After the storms this week in the UK we lost power for 48hrs
my UCM/4G is reporting:-

GSM Network Strength 0 - no network

if i put the sim card in my phone then it seems to send a txt
What else could I try?

[slychiu]

Try a complete power down.  Check that the sim card is properly inserted and makes contact and is not loose in the card holder.  
Do you have 2 antennas, and did you connect the 2nd antenna?

Is this a new gsm module?
