Power Cycling Franklin T9 Hotspot

I have exactly the same problem.  Our lake cabin in northern Wisconsin (where temps can drop to -35F. overnight) DEBE be monitored for temperature, and the Franklin T9 works, except when it doesn't.  Goes out to lunch same as others have described.  I've spent HOURS pursuing this with Tmobile tech support only to be told "too bad so sad” or words to that effect.

I’m going to try the solution proposed by DaveInRiverwood and see if it works for me.  I'll let you know.  Unfortunately, I'm in Arizona until late January, so for the next 30 days I'll just have to keep my fingers crossed and hope that the boiler in the cabin basement doesn't fail.

Hola, 

The timer option has worked for me. I give the hotspot power for 4-5 hours to charge the battery and then shut off the power with the timer. The battery does charge and drain daily but not completely. You don't need a costly router.

My T10 would shut down approximately every two weeks or so when I had the battery removed and constantly hooked up to electricity. The hotspot has been working since October and hasn't shut down. 

Same issue here, on vacation for 10 days and today my T10 seems to not be working, I can bet that the message says "charged too long", as I pulled the battery out trying to solve the "charged too long disconnect the charger" issue. I thought about the timer prior to leaving but could not find one in time.

I never had this issue with the old ALCAT, the new unit cost $150 and to have these issues is very upsetting. I called T-Mobile but they could not offer me any help but to manually push the power button.

Is there some code I can text to the unit to have it reboot ?

I used to run into the charging issue as well, where I'd lose connection once every two weeks until I went out an restarted the hotspot. This was a pretty tedious and annoying problem, since I live 45 minutes to 1 hour away from where my instruments are running on the hotspot. I figured I could trick the hotspot into complying if I just discharged the battery every so often. Fortunately, you can buy a $5-$10 mechanical plug timer on amazon (or at your local hardware store) that'll fix the issue. I set mine to charge and discharge every 30 minutes, and haven't had any issues in the past month. Not sure what the long-term impact to the battery might be, but I'm hoping the short 30-minute bursts will prevent it from overheating. Might be better to use longer time periods and fewer cycles, but I guess we'll find out eventually.

I've had the same problem with my remote location T9. Very frustrating. Has the timer trick worked for you guys? What about adding leaving a old phone at my cabin and using that as a hotspot?
