Hi,
Follow up question. We checked with TMobile. We can use our low tech flip phone to call the US from Austria and Germany. Our phone chargers (wall plug in) say:
"input 100-240v-50/60Hz".
"output 4.8v=0.4a"
Do I need a voltage converter or just the adapter to use this with our flip phones?
For calls, we plan on using Skype on our iPad primarily, but would like the phones as a back up plan.
Thank you.
Paul
