How ASDA compare for SIM only prices and benefits
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.
