Grade Mobile SIM only deals

Compare all of Grade Mobile's SIM-only plans, from flexible rolling contracts to longer-term deals with lower monthly prices.

Which Grade Mobile contract length should I choose?

It depends on how settled you are. Here's a quick guide:

  1. Pick a 30-day rolling SIM for maximum flexibility if you might switch soon.
  2. Choose a 12-month plan for a balance of lower price and a shorter commitment.
  3. Go for a 24-month plan if you want the lowest monthly cost and are happy to commit.
How do I switch to Grade Mobile and keep my number?

Order your new Grade Mobile SIM, then text 'PAC' to 65075 to get your porting code from your old provider. Give that code to Grade Mobile and your number will usually transfer within one working day.

Don't cancel your old plan yourself — the switch closes it automatically once your number moves across.

Grade Mobile is one of a number of smaller SIM-only brands in the UK market, competing on price for cost-conscious switchers. As with any lesser-known brand, the key considerations before signing up are the network it runs on, how its pricing compares with more established budget names, and whether the contract length and data allowance genuinely suit your usage.

1. Checking the network behind Grade Mobile

Smaller SIM-only brands typically run over the infrastructure of an established UK network under a wholesale arrangement rather than operating their own masts. Check which network Grade Mobile uses before committing, since this determines your real-world coverage.

2. Grade Mobile's contract options

Grade Mobile typically offers a range of terms, including 12-month and 24-month contracts, a 30-day rolling option, and unlimited data plans for heavier users.

3. Comparing against established budget brands

Weigh Grade Mobile's pricing against more established budget names such as giffgaff and Asda Mobile, since a smaller brand may offer competitive pricing but with less of a public track record.

4. Matching data to your usage

Use our mobile data guide to work out a sensible allowance before comparing Grade Mobile's prices.

5. Frequently asked questions

Does Grade Mobile operate its own network?
No, like most smaller SIM-only brands, it likely runs over the infrastructure of an established UK network rather than its own masts.

Is Grade Mobile cheaper than bigger budget brands?
This varies over time, so compare live pricing directly against alternatives like giffgaff or Asda Mobile.

Can I keep my number if I switch to Grade Mobile?
Yes, using a PAC code from your current provider, free of charge.

What contract lengths does Grade Mobile offer?
Typically a range from 30-day rolling up to 24 months — compare the specific options against your own plans.

6. Conclusion

Grade Mobile is worth comparing alongside more established budget SIM-only brands, provided you check the underlying network and match its data allowances to your actual usage. Compare its contract lengths and live pricing before deciding.
