First some background: I currently have Ting with 2 phones on sprint network. With my Galaxy S5 if I have LTE enabled my battery can drain some 80% over night. Can go a week without this happening or it happens every day. I assume it is connecting to a different tower when it does this massive drain overnight. My wifes Nexus 5 (I think its the first nexus 5 from LG) does this but not nearly as bad. To solve this I just keep the phones on cdma (3g). Since we rarely use data this isn't much of a problem.
The wifes Nexus 5 is near end of life. Battery can drain with no usage in less than a day. Doesn't matter what mode its in. Think its starting to show its age.
I am curious how well ting gsm network is at my house. Both Srpint and T-Moble show decent coverage in my area but my house seems to be on the drop off point between excellent and good. Leans toward good in real life.
1. Can I purchase a GSM sim and replace the sim in her phone. It was an unlocked Nexus 5 from google play.
2. If this works better can I take the same GSM sim and move it into any unlocked GSM phone. Either from Ting, google play, moto etc.
3. If it doesn't work any better I assume the newer phones can still be forced into 3g only mode, correct?
