Make sense of the plan before you commit.
CenterGuide explains UK mobile plans in plain language—monthly cost, data, contract length, scheduled price changes and switching basics—so you can compare the details that actually affect you.
Start with the decision you are actually making.
Instead of pushing one deal format, CenterGuide separates the questions: keep your phone, buy a handset, upgrade, or switch service.
Keep my phone
Understand SIM-only, eSIM, data allowances and contract terms.
Get a new phone
Break down device cost, airtime, upfront charges and total commitment.
Upgrade
Check eligibility, trade-in questions and what to compare before changing handset.
Switch service
Learn the steps for moving service while keeping—or changing—your number.

These examples are educational only. They show the types of information worth comparing before choosing a mobile plan; they are not live offers and are not linked to any network or retailer.
| Plan type | Example allowance | Example commitment | What to check |
|---|---|---|---|
| Light-use SIM plan | 10–30GB | Monthly or 12 months | Monthly cost, calls/texts, speed limits and roaming terms |
| Higher-data SIM plan | 80–150GB | 12 or 24 months | Total cost, scheduled price changes and fair-use conditions |
| Unlimited-data plan | Unlimited data | Monthly, 12 or 24 months | Speed restrictions, tethering rules and roaming limits |
| Phone + airtime plan | Allowance plus handset | Usually a longer minimum term | Upfront cost, device payments, airtime cost and total commitment |
Useful context before the sales page.
We organise information around the customer's decision rather than reproducing sales messaging. CenterGuide does not sell mobile contracts directly.
Price context
We separate the current monthly charge from scheduled future increases.
Usage context
We explain who may need 10GB, 50GB, 100GB or unlimited data instead of calling one allowance “best”.
Switching context
We explain PAC, STAC and contract checks before you move.
