Hi Pontus, still no joy here at all........

+UMNOPROF never sets to 1. It either comes back as 0 or 100 or 31. Never to 1 as I'm trying to set it to.
I've tried it so many times and have gone through the SARA Manuals and still the same result!!!!!

Re: LTE connection
Welcome to the wonderful world of uBlox AT commands 
If you can't select profile 1 it is the SIM card doesn't let you do this. This could be for any number of reasons.
Try running AT+UMNOPROF=? to see what valid choices you have.
Here's how it looks on my Connectivity board:
AT+UMNOPROF=?
+UMNOPROF:
0: SW default
1: SIM ICCID select
2: ATT
198: AT&T Profile 2-4-12
100: Standard Europe
101: Standard Europe No-ePCO
31: DT
19: Vodafone
46: Orange France
33: VIVO
45: TIM Brasil
44: Claro Brasil
OK
Now to do our restore of profile information you can select 100 temporarily or any other profile, in this stage the profile selected is not important, just that we switch to something different from what is currently selected.
AT+COPS=2
OK
AT+UMNOPROF=100
OK
AT+CFUN=15
OK
AT
OK
And then switch back to 0 for instance, by running:
AT+COPS=2
OK
AT+UMNOPROF=0
OK
AT+CFUN=15
OK
AT
OK
AT+COPS=?
+COPS: (2,"Tele2","Tele2 SE","24007",7),(1,"Telenor SE","TelenorS","24008",7),(1,"TELIA S","TELIA","24001",0),(1,"TELIA S","TELIA","24001",7),(1,"Sweden Mobile","MobileS","24024",0),(1,"TELIA S","TELIA","24001",9),,(0,1,2,3,4),(0,1,2)
OK
If profile 1 does not work and there is no specific profile for you regions/operator you can always use profile 0 and make changes to the settings if required.
