Welcome to public mobile! It's great to see you asking questions and figuring out how your service works with public mobile. Knowledge is power....the power to control what you spend and how to manage your account.
Everything here is pre-paid and with the exception of autopay if used to pay for your renewal it will attempt to charge you card once to pay for your plan amount minus any rewards or funds in your balance. Many of us top up our accounts just before renewal to ensure we never lose service just in case a rare autopay failure happens. You will still recieve the $2 autopay reward regardless of whether the card is used....vouchers can be used instead. You can learn more here on vouchers....

There are never any overages, extra fees or billing or hidden charges. If you want to purchase an add on you must add the funds to your balance first then choose an add on and submit it for purchase. If you want to change you plan you can schedule it to change on your next renewal or add the funds and change it now. Choosing "now" changes your plan immediately and starts a new 30 day cycle. There are no credits, refunds or proration of the unused portion of your plan.
To maximize your plans data alottment to get the most usage you should enable all of your data savings options available in your phone. Use your data saver, data warning and limiter options (these prevent data usage surprises of an app using high amounts of data unbeknownst to you and suddenly getting a data warning from pm that you have used 90% of your data.**) Turn off all background data in your apps as these can use up to 38% of your data. Background data is unnecessary for the operation of your apps. Turn off wifi assist or the android equivalent. Reset your billing cycle as per your 30 day cycle to keep your phone's data usage tracker as close to your data counter in your account.
Purchasing the $15/1gb data add on to supplement your plan data is a great option if you need small amounts of data near the end of your 30 day cycle as it will continue to roll over each 30 days until completely consumed and will then disappear from your account. However if you find you need 500mb+ extra per 30 days then upgrading to the $35/3gb plan (w/autopay) is a more econonmical option as you will recieve 2gb of plan data for only $10 more. Monitoring your data for your first cycle will give you a good idea of how much data you will need each cycle.
**Public mobile data usage warnings for plan data will not be recieved when you have a data add on in your account until 90% of all data on your account is reached.
