What can be done, if anything, if I can't get cell coverage in & right around my house? Work needs to get in touch with me often, & can't if I'm out in the yard. I checked the coverage map & it says there is coverage. I have verizon residential as well. Each plan is loaded. Is there any "booster" available to correct this? I just can't get cell coverage. I usually can get internet& email. Texting is a problem as well....my family lives next door. They have the same problem.
