Wifi calling is excellent BTW if you have access to it.
Not to hijack this thread, but I need to find a reasonable booster option for when I am boondocking off grid as there are parts of NE Iowa and in the Western USA where Verizon cell service is bad to nonexistent. I want to work at times when off grid. I need to look into this option again...same info/system may help the OP.
I have an older WeBoost Drive 4X. It works well enough in the boondocks, but has/had a couple of annoying issues:
1) It was originally advertised as boosting Sprint, but as it turns out, one of Sprint's primary frequencies was just outside of the range of frequencies that this thing boosted, so it really didn't boost Sprint. I switched to Verizon, and Sprint is now gone. I don't know if that frequency is still in use by T-Mobile, or if this issue has been fixed in newer models if that frequency is still in use.
2) When driving through a town and going by a cell tower, a strong tower signal creates feedback, and the booster shuts that cell frequency down to protect the booster. However, when far enough away from the tower, the booster does not turn that frequency back on automatically; a power cycle is required. This is rather annoying, because unless you are constantly checking the booster, you do not know if a frequency has been shut down. When traveling, one frequently goes through towns with good service, so the booster gets shut down frequently.
