Hi. My Global link 520 hasn't been communicating for over a month. Ive been told by my supplier that its a LTE-M network operator problem in the UK. I really could do with the network up and running to monitor my leisure batteries over the winter months in my motorhome which is in storage. When do you think normal service will be resumed and will the 5 year data sim be extended? to cover the outage?
@jokingjovial Regarding the GlobalLink 520. O2/Telefonica has blocked LTE-M data connectivity in the UK for all roaming partners, which affects (amongst others) Deutsche Telekom and in turn 1NCE (Victron's SIM provider). 1NCE originally communicated that this was not intended and that O2UK would restore service "as soon as possible", however appears not to be the case. Apparently O2UK's roaming agreement with DT suggests OSUK is not required to provide LTE-M coverage so they turned it off and are now re-negotiating with DT about the terms for providing LTE-M roaming.
Signs are positive that an agreement will be reached.
To be clear, Victron doesn't operate the LTE-M networks, so any question about service interruptions should be directed to the local LTE-M service provider - according to the GlobalLink coverage map, looks like that would be Telefonica Europe perhaps.
The Globallink has an internal sim card from 1NCE. ( https://www.victronenergy.com/media/pg/GlobalLink_520/en/cellular-connectivity.html ) However, if there is a LTE-M issue, thats not going to change with another sim.
You might be able to get a local LTE-M sim and install that for the time beeing. The page above also describes how to replace the sim and use your own.
Same issue for me here: https://community.victronenergy.com/questions/240370/globalling-520-suddenly-stopped-connecting-to-cell.html
Any updates for you?
Mine is still down. I was about to order a new LTE-M SIM, but after reading your post I reconsidered.

Thanks, yes, I'm looking at another provider for the SIM card currently.
Did anyone find a suitable LTE-M sim for the UK? My global link has intermittently connected to vodafone some how but isn't at all stable. Doesn't sound like O2 are going to bother resolving the issue so I've got an expensive chocolate teaput currently. No wonder someone was selling it :-D
I couldn't find a suitable alternative.
My Globallink has been offline for months now.
I ended up disconnecting the Globallink as it was also drawing a decent amount of electricity (mine is a small system) as other users reported here: https://community.victronenergy.com/questions/184427/globallink-520-power-comsumption.html?childToView=261256#answer-261256
Thanks for the feedback. Disappointing that I've spent money on a device that I can't use now. I wish victron would've made it support wifi at least since the chip their using supports it https://www.4gltemall.com/downloads/dl/file/id/216/product/1411/pycom_g01_specifications.pdf. Either that or they could approach O2 as an enterprise to see if they could at least start stocking/selling O2 LTE-M sim cards since I can't see a way of getting them as a consumer.
I'm not sure I'm going to get any support as Victron won't take support calls direct and I brought the unit second hand so the supplier/dealer isn't going to want to talk to me, not that they could help anyway!
The Globallink is still not working due to the LTE-M issues in the UK.
It is about 5 months now.
Questions: would the Globallink recognise a normal 4G SIM? I guess not. Is the only way to make this work to obtain an O2 LTE-M SIM? Is that even possible?
