In our review of ASDA Mobile, we said we liked the fact that ASDA share the same coverage and 4G speeds as their hosts Vodafone (5G is capped on their unlimited plans) as well as having WiFi calling and 4G calling.

They sell all of their SIM only plans as monthly bundles of mins, texts and data. This can be set to auto-renew every month. That lets you switch plans each month without being stuck on a contract.

In terms of price, they’re generally one of the cheapest providers, as well as having some of the most competitive small data plans of all providers on the Vodafone network.

ASDA still include inclusive roaming in these 36 EU destinations. Their low-cost data add-ons and extra parental controls also make them great for putting your kids onto a new plan.

Your ASDA SIM will arrive between 2-3 working days after ordering. Your SIM package will contain every size of SIM to fit into any phone. ASDA don’t offer eSIMs (here are all the networks that do).

It’s your right as a customer to get a refund for anything you buy online. So if you’re not satisfied with your ASDA SIM you can return it within 14 days to get a full refund. Here’s how you can do it.

Since you’re paying for everything up front with ASDA, you won’t have to pass a credit check for your SIM. All you have to do is set up an account with your details so they know who you are.

To switch from your old network to ASDA while keeping your number, you’ll need to request a PAC from your old provider and give it to ASDA whenever. For more details follow their instructions here.
