Compare to the other deal Huawei E5577:
They are very similar in hardware feature, but
* This Alcatel modem has unlock solution
* This ALcatel support 3G 850MHz and 4G 850MHz, which Huawei E5577 not support. So this one should work better than Huawei E5577 with Telstra and Vodafone sim if unlocked.
* This Alcatel comes with a wall charger.
Will this be better then Vivid wireless modem?
