Trying to do live streaming with a Mevo and the phone hotspot I've been using (Verizon) seems to be having connection issues. Anyone have particular recommendations for a hotspot that will work with pay as you go SIM cards? I only plan on using it 5-6 months a year and don't want to commit to contracts. Ideally, something that an antenna can be attached to. If it matters, I feel like AT&T has the best reception in my area.
