Samsung Galaxy Grand Max
If 2G & 3G to be used, do I have to insert 2 SIM's (GSM & CDMA)?
Is internet connection required on both SIM's?
Please reply
Hi,
You can inserty both SIM at the same time SIM 1 supports 2G/3G/4G and SIM 2 supports 2G/3G
Hi there! Both SIM slots use the regular SIM (not CDMA). I'm sorry but I fail to find information if 2nd SIM slot supports 3G and 4G.
