MF60 for us
We used an unlocked Three E586 for years whilst travelling, but in Australia Telstra's "Next-G" network uses an unsupported frequency so we picked up a rebranded MF60. In comparison:
- MF60 is more reliable (the E586 drops out and needs a reboot every few hours)
- MF60 feels more solid, is thinner and has better battery life
- the web interface of the E586 is better than the MF60, but we really only use it to change APNs when swapping SIMs
- the Telstra interface of the MF60 doesn't support sending and receiving SMSs but the unbranded ZTE interface does
- both types can be unlocked for a few £s online
Picking up a cheap data SIM (e.g. €10 for 1GB-1mth in Austria) and connecting all the iPads, Blackberries, laptops to it when travelling saves a bundle on hotel internet and roaming fees.
If our Telstra MF60 gives up its life, we will definitely look at getting an unbranded one to replace it, hopefully an LTE MF90 will be out by then!
