everything worked from day 1 EXCEPT my £4monthly plan -I had to purchase £5 of credit to get started then pay the £4 monthly ? will I get my £5 credited to my monthly plan?
Absolutely rubbish customer service seemed to ignore all correspondence or just didn't read Hoping this terrible level of service was caused by A I and not humans
Quick and easy to change over from our previous provider to Asda mobile

Every month I buy a bundle and set it to recurring. Every month it fails to renew meaning I go a day or two with no phone use. This month I decided to not choose recurring to see if it worked just buying a new bundle when my existing one ran out...this didn't work either, I was charged £10 but it just said activation needed but something went wrong when I tried to do this. As I needed to make a phone call I topped up with £10 credit until I could sort the bundle problem. I phoned asda and they said to switch off my phone and they would sort the bundle. They did sort the bundle but with the extra £10 I purchased for credit so now I have been charged twice and paid £20 for a £10 bundle
The sim card works nicely but your web site was hard to understand and navigate. The information about the sim cards and the packages wasn't very informative and it would probably be helpful if it was put on there that you need to create an account first. Because I put in my details so it would deliver my sim card but because I hadn't created an account it wasn't working and it didn't say anywhere that I needed to create an account first. After I got an account it said that my free sim card would arrive shortly but it didn't. After a couple of weeks I bought a package and then the sim card and package arrived quite quickly. It would have been helpful if it had said that I needed to buy a package first, but other wise I'm happy with the service.
Extremely friendly customer services who didn't transfer my number to my new SIM, didn't call me back, didn't arrange for a manager to call me back and repeatedly failed to complete my phone number transfer in the times they promised in repeated phone calls following missed commitments. I'm still waiting to hear how they're dealing with the complaint I asked them to raise 9 days ago.
I had a problem with use of my credit for package charge. It should be automatic but failed. A kind gentleman sorted it out.
The sales advisor was first class
Really helpful person on the phone, patient and understanding.
Bought for my grandaughter for her trip to Paris. But she couldn’t get data roaming to work
All good, thank you.
Outstanding service - Was O2 for years and I wish I transferred to ASDA Mobile sooner. Thank YOU !
Price is right. App is horrible , dont understand how can U overlook this detail
Simple,easy to use and inexpecive
It took just under 3 weeks for my SIM card to arrive.I rang them said they had difficulty getting Sims it arrived 4days later.Put SIM in entered PAC number it then took around 55hours before sim was activated.I not had any problems once activated.Tbink I should have been informed if delay in getting SIM activation .
