Sits there activating Sim, cant connect. EE Support have tried multiple things. I’ve tried changing IMEI to my iPads in the hope EE were blocking the original, no luck.
Anyone got it working?
You say “activating”. Do you actually mean activating. For example, has the SIM been tested working in your iPad/phone?
I don’t have the X3000 but I tried an EE in a Puli and Spitz and it works with the APN “everywhere”, no authentication needed.
In my X750, it works in both QCM and QMI mode, port /dev/cdc-wdm0.
It might be worth grabbing the latest (beta) firmware GL.iNet download center, and giving that a try
Sim is activated. Works fine in an ipad. I’m on latest beta firmware and have upgraded the modem. Using APN everywhere with no auth.
Out of interest, is your EE sim data only ? Mine is, EE Tech Support are sending out a regular mobile sim today.
Hi Guys
I had trouble with a Talkmobile sim with Data, texts and minutes in my GL X3000.
When it worked, it was good, but didn’t pick up the APN setting and didn’t stay connected reliably. The operator said that there were no restrictions, but did say that the sim was designed for Phones.
So I tried a Smarty (3-network) data only sim and this has worked for about 1 week, so fare, so good 
During my struggle the GL team informed me that there is some comparability with some Apple devices. However between the GL App and my iPad this was ok.
The other useful thing was a link to a website;
APN settings for the UK.
So fare I have used 37 Gbites of data on my Smarty Data only Sim £20 p/m.
This is all so that I can locate my router at my caravan on the Isle of Wight where I know there is a 3-Network tower reasonably close.
Hope this helps
Best wishes
