HTM M3 As a Second Phone?

[Nickdi]

Want to buy a second phone, so don't expect too much about the performance. My current one is Huawei p6.

Come into this HTM M3, sounds not bad according to the video, but not sure about the power life.

What's most that attracts me is that it would only $39.99 if I get the flash deal. So, what is you guys suggestion?

For my work SIM card. Don't want to use it with my private number. If I can't get the flash deal, any other suggestion？
