Maybe someone more knowledgeable than me can suggest a direction to go for me before I spend money in wrong places.
I work on heavy equipment in field mostly in GA. It's mostly in rural remote places . I keep a RV at jobs and travel to other close jobs in service truck . I've tried AT&t ,Verizon, sprint,etc.. and currently have family mobile thru Verizon simple because it's had same service and way cheaper . I need something to ether boost a signal or ??? I am having trouble downloading manuals and using phone in several ares I work . Without keeping 4 different sim cards and climbing up tree and holding phone looking for better signal where do I start ? I've looked at boosters and the money isn't a problem ( I don't want to spend thousands and then spend hundreds every month though) something mounted in rv would work or in service truck since it would obviously be close to rv . Any suggestions??
