Did Verizon connectivity ever get added? Haven't seen an update.

@BrettMargo It was added. Unfortunately, I will only speak for myself, I was led to believe it would be available to everyone. It is only available to Enterprise customers AFAIK at the present time. Last I was told, they hope to add it for all in the future. I would not hold my breath.

Yep definitely not holding my breath. I saw they added it for Enterprise customers which is about as useful as them not adding it at all.

Particles justification that it only improves connectivity on a limited number of devices is flawed because they don't account for all the devices that aren't deployed to a large number of places because there isn't AT&T or T-Mobile coverage.

NTN LTE will fix this eventually but until then we're out of luck.

That is not the only logic that is flawed. I have had numerous people pass on buying my product because it uses AT&T. So, I am caught in a catch 22. I can't afford to become an Enterprise customer because I don't sell enough product. Can't sell more product because I am not an Enterprise customer.

I have to drive to a remote location to test my devices before I send them out the door because I can't always connect to AT&T from the office.

Agreed, we are out of luck.

That's annoying. Have you tried using a higher gain antenna? Some of our customers have had success with these in remote areas. Even if you only use it for testing could save ya some driving. https://www.amazon.com/Electronics-311125-Dual-Band-Directional-Connector/dp/B00KY4Q7DG/ref=sxin_2_sxwds-bia-wc1_0?keywords=wilson+antenna&pd_rd_i=B00KY4Q7DG&pd_rd_r=a3ed4dcc-0e65-41df-89a3-4c50c5fa0c2a&pd_rd_w=qrv5W&pd_rd_wg=BV5di&pf_rd_p=39e7c2a0-69e1-4a3f-8d8f-4c4ee1aefdb5&pf_rd_r=SF1VFBWBCEQC0HAE2SHC&psc=1&qid=1571334195

It is very annoying.

I have tried some other antennas without success although not this particular one. I'll try anything at this point!

Thank you

I believe it's SMA male so you'll also need an SMA to UFL adapter cable. Double check that though. I always get confused between SMA and RP-SMA.
