Data SIM for Internship abroad
at the moment I'm doing an internship in Atlanta. I'm from Germany and brought my Nexus 4 with me.
I arrived 3 days ago and now it's time for me to get my phone connected. I can only use wifi right now and that's buggin me.
I only want to use data as I have the possibility to call anyone from my phone in the apartment. And that's enough.
So texting and talking is unnecessary to me.
What are my options? I was thinking about this offer: http://www.walmart.com/ip/T-Mobile-SIM-Kit/24099996
Is there any better / cheaper way?
Are there no SIM Cards available that provide Data only? What about tablets? How does that work? Are SIM Cards for tablers compatible to Smartphones?
Why is this phone thing so complicated in the US?
Thank you very much in advance.
