Frequently asked questions
- How can a plan cost less than $20 a month?
- Plans in this range are usually metered rather than unlimited, or use promotional pricing for the first months. Some are cheaper when you enable autopay.
- Are these plans suitable as a main line?
- They work as a main line if your data use is low or if you spend most of your time on Wi-Fi. If you stream video on mobile data every day, check the cap before switching.
