I will be travelling to the United States around May and I would be staying for at the most, 1 month. I need a data only plan (SIM only) for an old T-Mobile Sonic 4G Mobile Hotspot. I would need unlimited 4G internet which I could use with my hotspot device. Which plan should I avail?
From my research, I think the wisest is to get the 70$ unlimited 4G + 15$ for the wifi tethering/sharing.. is this the best approach?
