Instructions: Given a travel related situation, and given a specific question about the situation, summarize the question into a title
Input: I'd like to fly to the USA at the end of January and I was wondering if my phone (Elephone P7000) supports any of the frequency bands in the USA.

I am flying to Cary, North Carolina and my phone supports dual-sim with these frequencies:

GSM: 850/900/1800/1900 MHz
W-CDMA: 850/900/1900/2100 MHz
LTE: 800/1800/2100/2600 MHz

What network will I be able to use? Which sim-card is obtainable from Germany that is useable in USA? I'll be there for three days, so I won't cause much traffic.

Output:
Using mobile internet with a Elephone P7000 in the USA
