What to include
- A needs card with data quantity, upload-rate threshold, device/use requirements and unknown coverage marked separately.
- Three complete twelve-month comparisons including promotion periods, equipment, setup and stated excess-data charges; one changed-use recalculation.
- A revised decision after the supplied availability replies, an unsent provider question and one provisional backup route.
Review and revise
Use these criteria to check your work and choose what to improve.
- GB/MB quantity and Mbps rate are never treated as the same unit; the supplied task constraints are retained.
- Every month and one-time cost is counted once, and partial excess-data blocks follow the supplied fictional rule.
- The decision changes when the relevant need or availability changes; excluded plans have a named reason.
- Real availability, compatibility, performance and assistance are kept pending until verified; no purchase, free service or subsidy eligibility is claimed.
Three ideas to help you along the way
Three useful ideas
The rules behind the steps.
Start with the task
List the data, rate, device and location requirements before comparing offers.
Compare the same period
A first-month advertisement and a twelve-month total answer different questions.
Treat access as a gate
An inexpensive plan that is unavailable or incompatible cannot meet the stated task.
What do these words mean?
Key words
Key terms worth knowing.
- GB
- Gigabyte: a data quantity. This course uses decimal units, so 1 GB is 1,000 MB.
- Mbps
- Megabits per second: a data-transfer rate, not a monthly data allowance.
- Upload
- Transfer from your device toward the network, such as sending a file.
- Introductory price
- A price applying for a stated starting period before another stated price applies.
- Data allowance
- A stated quantity included for a period; extra-charge or performance rules depend on the plan.
- Hotspot
- A device’s sharing of its internet connection with another device; compatibility and plan terms need checking.
