I unlocked my Galaxy s5 and g/f's s3. We plan on using a prepaid micro-sim while we are in France such as those from SFR.
What network options should I select for fastest browsing? Under settings>more networks> network mode>
- CDMA
- LTE/CDMA
- GSM/UMTS
- Automatic
Which is best for Europe (just GSM?), how should I have it set when I am in the US?
