Librem 5 - LTE Bands support for US


#1

When will Purism release a complete list of supported LTE bands in US ?
I need to know ASAP , because I’m frustrated with ATT coverage and desperately need to switch back to Verizon. On top they are offering 250 per line to do so. :slight_smile: But, it would be the dumbest move , if my daily driver (librem 5) won’t have the signal in all areas covered by the carrier.
Would appreciate some response by the tech support here,
Thanks

Here is a quote from a support technician

His original quote links to

which says

But keep in mind that this may not be the only two modems used:


Table source for anyone who’s interested. I just did an inspect on the FAQ entry, copied the HTML, and manually add in <td></td>:

Thanks a lot!

I just hope that they make a super quick announcement once they decide on the final modems going into the phone and what other bands and frequencues it may support.


#4

Yes, I hope for this too. The use of Gemalto PLS8 modem means in my network, I can’t even get normal calls and texts as the modem does not support UMTS B4 (1700/2100 AWS), a requirement for my network.
Scratch that, the US modem supports WCDMA BAND4 which seems like UMTS B4. But the current modems still skim out some of my supported LTE bands


#5

So these are currently supported bands by 2 major carriers in US

AT&T 2, 4, 5, 12, 14, 17, 29, 30, 66 | freq 1900, 1700 abcde, 700 bc
|Verizon Wireless 4, 5, 13, 66 | freq 1900, 1700 f, 700 c

So, the support provided with this current modem is insufficient and I see no reason to use this phone at all. Unless they add more, I’ll cancel my pre order. I need a phone , not an iPod w some mobile connectivity.


#6

I use T-Mobile and it seems they may have bands available.

I plan to switch my provider to suit the phone if T-Mobile is insufficient.

I guess it depends on your priorities.


#7

Priorities

Make & recieve calls
Quality Broadband access where and when available
Privacy
Battery life

What’s the point of having a great phone, if it’s gonna leave me stranded somewhere or make me miss important calls or had them disconnected. I’ve been there already (with some unlocked and “uncertified” devices), that’s why I’m concerned.

To have the best coverage not just where I live , but county, state wide and across the whole country, means 2 carrier choices - ATT or VZW.
Then you gotta have a phone which will best utilize the coverage provided.

The only way I see sticking with this pre order is either having the purism team add all the bands for any of the 2 (ATT / VZW) or me deciding to spend $600 on a spare phone - mostly connected to the hotspot of the primary one. I just can’t have a crippled daily driver, even if my job - livelihood wasn’t depending on it. :slight_smile:
