Well, one of them anyway. I'm going to Africa soon to work in an remote area with poor 3G-only coverage, 900MHz E-GSM and 1800Mhz DCS, so I was thinking of taking over a booster to mount on a nearby hill to improve coverage. Problem is the usual cheapies (it's going on a one-way trip so I don't want to spend a fortune) from Aliexpress have such a mishmash of claims that you can't really tell what you're getting, they throw around 2G, 3G, 4G, DCS, UMTS, LTE, and anything else they can think of at random. Can anyone tell if any of the following will meet the requirements?

Reason for those particular ones is that they offer fast shipping, I'm going on rather short notice.
