There's no ONT... ONT = Fiber
The Cellular modem is located inside the ISP equipment. It pulls the WWAN from the tower and then converts it to Ethernet to plug into devices directly / WIFI is internal to the box as well.
$25/mo is a good deal if it delivers decent speeds that are livable. I went TM because I test them all of the time with different MVNO's and consistently got 500+/100 speeds when testing. TMHI however the best I've hit so far has been 350/100 and it does vary depending on time of day. When testing VZW though with their in house MVNO Visible though the speed wasn't really there maxing at 20/10 maybe 25 DL at the right moment. When traveling around the city though and testing randomly it varied quite a bit and in Best Buy 2-3mbps which is ridiculous. Even in a VZW store with a micro-cell in the store it was pitiful. Having worked on several different carrier networks over the years though with some inside knowledge of how they operate helps in figuring out the perks and pitfalls of each of them. They've changed quite a bit over the last 10 years though and especially with LTE / 5G being implemented. The VZW tests though were within the last year or so and it was a bit shocking after seeing speed tests standing next to VZW engineers and seeing the results I expected them to be much better.
Now, they might have been reducing speeds by throttling the Visible SIM vs their in house VZ Red. I went to BB to check the speed issue with a VZW approved phone model they sell and the results were the same which ruled out being a HW issue. Things are always evolving though.
I'm finding some quirks with these gateway devices though the more I test and use them. This morning I was downloading a bunch of stuff and it was hitting ~70mbps and I was wondering if it was a source issue or the service. I rebooted the gateway and it shot up to ~350mbps instantly. So, with a cable modem that's usually not the response or case but, these gateways seem to like to be power cycled often for some reason.
BTW I ripped the gateway apart before even plugging it in to see if it worked to get a grasp on how things got jammed into the case and any improvements I could make. It's still sitting w/o the casing on it and I hooked up some different antennas to it to position them better than the PCB slabs they had inside. I disabled the WIFI on it to not compete and keep it running cooler.
So, the quirky thing about this particular device is 4 antennas on both LTE/5G and WIFI6. 2 antennas are for the LTE side and 2 for 5G. Same on the WIFI side for 2.4/5. For some reason there's a GPS / BT antenna as well. They don't make sense to me as the device doesn't need either of those for any particular reason. But I used some pigtails to extend the wiring out to the antennas and some flexibility in placement. By moving the placement of the antennas different aspects of the signal change accordingly. I started with all of them UP in a vertical position and that was worse than their current positions in the photo. Testing different positions ranged from 200mbps up to the current 350mbps. I'm still trying to pin down the LTE side though as there's a note on the monitoring tool I'm using that CA (carrier aggregation) should be available to get even higher speeds. Also, the specs on the modem inside is capable of 2.5gbps / 300mbps so, there's room for growth in terms of bandwidth.
