I currently have a Blu Win HD LTE Dual SIM. With this phone, I can set either SIM for the data connection and get an LTE/3G connection for that SIM. The other SIM will be forced to use a 2G connection. I was using my personal SIM for the data connection and my work SIM as SIM 2 and only used it for phone calls. Well, my company doesn't allow a 2G phone to be used as a company device.
How does the 640 or 640XL dual SIM operate? Can I have two 3G connections or will it be the same configuration - one LTE/3G connection and one 2G connection?
