I have WeBoost 4G-x and S8+ Galaxy phone. Zip 49903. I get 4G and 3 bars, then it drops to 1G or 3G and slow crummy service. Vol/power reset did not fix issue. Toggling Airplane mode makes no difference. I have to Restart to get back to 4G, the it reverts to 1G or 3G in a minute or two. Any help would be appreciated.
