WWAN Fibocom L850-GL to receive phone call

2019-11-27, 22:34 PM

Hello, 

 

 

I considering buying a THINKPAD X1 CARBON (GEN 7), the Fibocom L850-GL 4G LTE CAT9  is included in the price, I guess it is used to acces 4G network with a SIM card exactly like a smartphone.

 

But in this case I want to receive call on my number, is there a way to connect to GSM network? (even doing call but some may say to use voip)

 

Please feel free to explain if I got this wrong Smiley Wink

 

Thx

Hi ,

 

Thanks for showing interest in ThinkPad X1 Carbon 7th Gen.

 

Receving calls from the SIM-Card is possible as long as the modem is capable with 2G network. Hence, you may use VoIP to receive calls if 2G option is not available from the installed modem.

 

Regards,

Thanks for your reply. I'd like to get an answer to my original question. Does this modem (Fibocom L850-GL) support 2G?

L850-Gl is a pure data only card, does not support any voice.

Either native cellular voice, or VoLTE voice.

 

There are only three functions for this card: data, and SMS message, and GNNS location service.

Thanks, how can I confirm this information, do you have any sources?

 

Supported

  • data => tested working
  • SMS => tested working
  • GNNS => I don't know how to test it on Linux

 

Not Supported

 

  • native cellular voice

  • VoLTE voice.

 

Have you succeeded to test GNNS on linux ? I can see it in the modem manager gui but wasn't able to get my location.

 

Also, I have ordered a onesimcard (www.onesimcard.com), and the person told me that the SIM won't work because of each country partner bands so I do not support the correct bandwidth. I found it strange because the Fibocom L850GL is very new.

 

This is an international SIM card. Does this man means that only native cellular voice won't work ?  Can I receive SMS and DATA everywhere without having to check bands? Otherwise, what bands can't I use?

 

Sorry this information is not very clear for me....

 

Please answer to me like a kid who's discovering mobile cellphone.

 

Thanks
