1. Heavier than usual cellular traffic. There’s really nothing you can do about a saturated cell tower but wait out the phone traffic. It’s a numbers game- the more phone traffic that fights for that same spot, the weaker your signal becomes.
2. Building material. The primary reason for a weak cell signal is the materials that surround you. Whether you are home, at work, in a shopping center, your cell phone is struggling for signal access. Metal and tinted, low-E glass are the two main materials most responsible for a degraded cell phone signal. You’ll notice when waling around that if your signal improves, you are usually by a door or window rather than metal construction materials that blocks your phone’s signal.
3. Low Battery. Your phone needs actual energy to maintain a connection. The higher the charge, the better the connection. Keep your phones battery at optimal charge.
4. Bad weather, geography, cosmic events. Cell phones operate via electromagnetic waves which can easily be affected by weather (thunder, lightening, wind, rain, snow, etc.), natural obstructions (hills and mountains commonly impact cell phone reception) and cosmic occurrences (such as sunflares).
5. Blocking your own antenna. The bulky, shoebox-sized cell phones of the early days of mobile communication were surprisingly better at connectivity than today’s sleeker models. The early phones had exterior antennas- making the reception fairly consistent. Today’s cell phone antennas are embedded inside the phone. You can effortlessly and unknowingly block the antenna and lose your signal. You can easily search online for the exact location of your phone’s antenna and once known, inadvertent blocking should be significantly reduced.
