- Yes. It is prepaid. You would need to add money first, then pick a PBTD (pay by the day) plan.
- Straight off of T-Mo's website: When do I incur charges with a Pay By The Day plan?
A: Plan charges are applied to your account only on the days that you use your service. All services expire at 11:59pm. (local time) Days that your service is not in use, your account will not be charged.
That means that yes, anytime you make/receive a call or text or use data, it will trigger the daily charge. You can turn data off on the phone if you have a smartphone. You can leave the phone on and let it roll into voicemail whenever you don't want to answer so you don't get charged.
- There is no "auto switch"; you would select one of the three available plans, and T-Mo will charge you when your usage triggers the daily fee. You can switch between the plans if you'd like if you anticipate needing web for one week but not the next. T-Mo is not going to automatically switch you between the plans to save you money
Lastly, welcome to HoFo! Another perk of T-Mo is their WiFi calling feature. Great if you have WiFi at home/work but poor coverage, since you can do voice/text/data over WiFi instead.. assuming your phone is equipped to do so of course.
