Grade Mobile 12-month SIM only deals

Lock in a lower monthly price with a 12-month Grade Mobile SIM-only plan, offering a balance of savings and commitment.

Why pick a 12-month Grade Mobile SIM only deal?

A 12-month Grade Mobile plan strikes a balance between price and flexibility — it usually costs less per month than a rolling 30-day SIM, without tying you in for a full two years.

It's a sensible middle option if you're settled on Grade Mobile but don't want a 24-month commitment.

What happens to my Grade Mobile plan when the 12 months end?

Once your 12-month term finishes you're typically free to leave, switch to a different plan, or carry on month to month, so it's a good time to compare the market for a better deal.

Setting a reminder near the end of your contract helps you avoid rolling onto a pricier out-of-contract rate by default.

A 12-month term with Grade Mobile sits between the flexibility of a 30-day rolling deal and a longer 24-month commitment, typically offering a better price than the rolling option without asking for a full two years upfront.

1. Why choose 12 months with a smaller SIM-only brand

Committing for a year with a smaller brand like Grade Mobile can unlock a better rate than its rolling monthly option, while still returning you to the open market within a reasonable period to reassess pricing and coverage. This suits anyone reasonably confident in the network behind Grade Mobile for the year ahead.

2. Checking the network behind Grade Mobile

Before committing for 12 months, check which established network Grade Mobile actually runs on, since this determines your real coverage regardless of the brand name. A year is long enough that poor signal in your area would be a genuine ongoing frustration.

3. Comparing against Grade Mobile's other terms

Compare this 12-month option against Grade Mobile's general SIM-only range, its 24-month deals, its 30-day rolling plans, and its unlimited data SIMs to find the right balance of price and commitment.

4. Matching data to your usage

Use our mobile data guide to estimate a sensible allowance before comparing Grade Mobile's specific plans and prices.

5. Frequently asked questions

Is a 12-month Grade Mobile contract cheaper than 24 months?
Typically the monthly price is a little higher than an equivalent 24-month deal, in exchange for a shorter overall commitment.

What happens if I need to leave before 12 months is up?
You'll typically need to pay for the remaining months, so only commit if you're confident about your plans for the year ahead.

Can I keep my number when switching to Grade Mobile?
Yes, using a PAC code from your current provider, which they must supply free of charge.

How do I check Grade Mobile's coverage?
Check which established network it runs on, then check that network's coverage for your specific area.

6. Conclusion

A 12-month Grade Mobile contract offers a reasonable middle ground between price and commitment. Compare it against Grade Mobile's other terms and confirm the underlying network's coverage in your area before signing up.
