Most people buy the plan they might need rather than the one they use. Check your last three bills for actual usage before switching.
Mobile plans are priced monthly and judged monthly, which is exactly why they escape scrutiny. Forty dollars a month doesn't feel like a decision. Four hundred and eighty a year does.
The bigger leak is usually data you never touch. Most people buy the plan they might need rather than the one they use, and the gap is money going nowhere. Check your last three bills for actual usage before switching anything.
Frequently asked questions
How do I find out how much data I actually use?
Your provider's app or your monthly bill will show usage per billing period. Look at three months rather than one, holidays and tethering can make a single month unrepresentative.
Is a cheaper plan always better?
Not if you go over and pay excess. Work out your genuine average usage first, add a little headroom, then price against that. Paying for 100GB you never touch and paying overage both cost money.
