North Texas iPhone 5 user here (soon to be 6!). Yesterday, and so far today, my phone has not connected to the 4G LTE network. I have had no problems connecting with my phone to the 4G network in the past at home in Garland, driving to work on the George tollway, or at my office in Plano (near George/North Dallas Tollway intersection), but I haven't seen the LTE connection on my phone in over 36 hours. Nothing with my device has changed (no drops, damage, water exposure, etc.), so I'm pretty sure something else is going on. Help!!
