This phone has been my home internet for the past 3--1/2 years.
It's a Blu Life One X LTE with a non-removable battery and it's been plugged in continuously for all those years-- and the hotspot has been turned on for that entire time, as well.
It's performed flawlessly and still works fine, but the battery is so swollen that it popped off the back cover.
I've removed the non-removable battery and would love to put this back in service but, unfortunately, I can't find a replacement anywhere.
I'm going to be sad to say goodbye to Old Faithful.
Wow, I'd be afraid of using that battery for sure. I like the solder idea. As long as it is similar capacity, it should be fine I would imagine. Then again, all I know is that I know nothing. Best do some research. Good luck finding something similar that you can place in there!
It's a grandfathered T-Mobile plan with unlimited talk, text, data, 14GB LTE hotspot and unlimited Binge On (which means that most major video services don't count against the 14GB) that costs us $37.50/mo.
For a long time we used the phone, as is, but eventually transitioned to using PdaNet+ and Connectify with it to bypass the 14GB limit.
So we no longer have to be careful with our non-video data usage.
I signed up for a line with Visible and have been test driving it for the past 5 weeks. It's working very well, for us, and I'm trying to work up the nerve to cancel T-Mobile.
T-Mobile has been bulletproof for us, for a long time, and it's hard to pull the plug. Hard to beat the $25 price of Visible, though.
I'll keep them both for another few months before giving up a plan I could never get back.
FWIW: I throttle bandwidth in our router in such a way that we can watch 3 TV shows in SD (good enough for us) with 1 GB of data.
By keeping our bandwidth reasonable, we stay under the radar and have had zero problems using cellular for home internet.
I know Chelle can handle almost anything.... but I wouldn't recommend soldering a Li-Ion, or any rechargeable battery unless one is pretty comfortable with soldering skills. It's not a beginner-level project, and they can explode if overheated in the process.
(Reference: I've soldered plenty of NiCad, and a few Li-Ion, packs in power tools, and I have pretty extensive soldering experience.)
