With 4G, to determine fidelity of the connection between the modem and the tower, I prefer to log into the admin interface of the modem. In my case this is http://192.168.1.1/ where I can then see that my RSSI is -55dBm and I am on 1770MHz channel using 4G+ protocol. To me, these metrics indicate a high quality of connection between me and the tower.
I am glad some geeks have noted the time-wasting nature of rebooting a modem when it's obvious that the problem is a contractual issue with the upstream provider not buying enough bandwidth for peak times.
That said, WN's unlimited add-on is not a bad deal, even if the connection is only usable between midnight and 5pm. For me the problem is that it can only be used in their modem which adds to my power budget and reduces my ability to control the routing and data. They don't, for example, allow setting the DNS servers to be used in the provided modem.
As a full time roaming geek, I just called Vodafone and asked how to get more than 100GB. They explained that the companion plans each come with 100GB. This means that I have ordered 3 sims that each have 100GB for a total of 300GB at the reasonable cost of $160/mo.
For me having multiple sims isn't that big of an issue because I am putting them into a Pepwave MAX Transit Duo which allows me to configure rules for when and how to use any of the 4 sim cards that its 2 LTE-A modems can access.
On heavy work days I will use 15GB of data. I am happy to pay for it but it's difficult to find anyone that sells mobile data for less than $10/GB. For a while I was using Spark's 24hr unlimited data boost on work days. That's basically unlimited data for $200-300/mo but it's tedious to have to buy the add-on each day and make sure to time it while I am not in a meeting.
Vodafone have really broken away from the pack with their Extra Large monthly plan. The current setup is $0.53/GB compared to 2degrees $8.25/GB in their ($99 for 12GB data add-on).
In case you are wondering: I already tried load balancing with two sims that were throttle at the end of endless data. While it is 2.x Mpbs, it also seems like the latency is artificially increased. I don't have metrics to prove that. It was just a perception.
If you are still reading this and have any suggestions then please share. Unfortunately, I can't used fixed wireless due to the nature of my living situation.
Thanks!
