A 4G Antenna / repeater is an option.  But would need to to coordinate with telecom to put it up.  They will gladly take your money to improve their infrastructure.  Time and cutting thru red tape to arrange such a thing is an issue (government involvement to put up a structure).  Plans in this country are also somwhat expensive for data, but somewhat coming down in price as of late.  Cheap electricity = remote = bad infrastructure for tech.

Thanks for your interest and posting though
