My telco just informed that in a week's time, my data SIM
card's plan will be upgraded from 3G to 4G LTE.
Was told by the Telco that:
a) I don't have to swap the SIM card: the same existing
3G SIM card will auto-support 4G LTE without the
need to change SIM card. Is it true that a 3G SIM
could support 4G LTE (just the Telco needs to set
/program my number to 4G LTE) ?
b) the Huawei USB modems that I have are E220 &
E173. What's the lowest-cost Huawei that support
4G LTE? What's the lowest-end Huawei that works
with USB 3 ports? I'll need a dialler version that
comes with the Huawei modem that supports
Win 7 64bit, Win XP 32bit & OS-X Mountain Lion
(or newer OS-X)
c) What's the lowest end Galaxy Note & iPhone that
support 4G LTE tethering? (ie use the phone that
has a 4G SIM card in it as Wifi hotspot sharing)?
What's the lowest version of Android & IOS needed
to support 4G LTE or it's purely a hardware matter
that's not related to the OS of the phone?
