We live in Canada and always buy Asda mobile sim cards when we come over. Very dependable service. Very affordable, can't say enough to recommend them highly
I have no problem with coverage. I have a sim in my phone and one in a box which I use for house WiFi. The main issue I have is with frequent technical problems, logging in, payments not going through for recurring bundles. In their favour, I have no problem speaking to a human and the issue is always resolved. But Asda, please fix your frequent technical issues.
Signed up for a sim only deal, got the contract, setup direct debit, told l would get sim 2-5 days. No sim delivered after 8 days so cancelled contract wirhin 14 day cool off on the phone to you. Was told the sim not sent out as contract no set up properly, even though l got a contract and set up DD and told sim in the post ? Also, Cancelled the direct debit as didnt want any issues with payments coming out if someone had intercepted the sim in the post. A week later a sim arrived at the house and now you are sending me these emails. Very poor service and customer service and will not be recommending ASDA mobile..

Asda sold me a Mobil fone contract which relies on Vodafone. It has zero to poor connectivity in Small Heath Birmingham! I was unable to open emails, whattsapp or do a Google search! It took four hours to back up whattsapp! Absolute nightmare! The asda superstore wifi at small heath also uses Vodafone - their systems stay slow or down, inconveniencing customers! Appalling kaffuffle with tech people re data connectivity..playing around with fone settings- akin to rearranging chairs on the titanic! I had to buy a lyca sim card and data (uses EE network), just to deal with asda over the contract issues! I love asda and I don't expect this from them. Asda won't refund or compensate other than £5 credit- I can't bail out fast enough - the £5 credit is useless!
Easy to purchase a PAYG plan from the website. I purchased from Asda as they use the Vodafone network which has strong signal in my area in comparison to other networks. PAYG prices are also good.
Everything is great about Asda mobile it does what it says on the tin
In spite of multiple phone calls I just can't get the Asda app properly set up or use the roaming. Very frustrating
Following on from my previous review and as of today still no network. I arrived in Greece on the 15th June and it's the 21st June. Three calls to customer care and one call returned and they still can't fix the problem. I was told I was being handled by there technical team and I was a high priority. I would also be compensated. In the meantime I have to suffer having absolutely no network. Asda didn't bother to call me yesterday on another number i provided them. I return back to England on the 27th June then fly out to Rhodes on the 3rd of July. This simply cannot continue and I will have to contact the ombudsman to review my options available.
I found it impossible to get the deal I wanted, paid at least as twice as much as I wanted to for less data than I needed and the "helpline" really should change its name! (One of the helpers even said "isn't there someone you can get to do it for you?")
l have been a customer of Asda mobile since early 2022. lhave my new debit card thus my direct debit failed to receive money to Asda mobile. Thus i phoned Asda who took my detail of my new card and in no time it was sorted. Even I have received message confirming my monthly payment has gone through. Thank you Asda.
Had an issue topping up gave customer services quick ring all sorted and back online in minutes
Excellent service
The hardest thing about transferring to Asda sim only contact was getting my sim out of my phone!…🤣🤣 So straight forward the wife is now changing!.. EU roaming works perfectly no extra charges. Would highly recommend swapping over to Asda now saving £22.00 a month bargain!..👍👍
Another month, same problem. Friendly call centre but no in management cares. The call centre team manager tells me the exact same thing the team says " we are working on the issue with NatWest, Santander etc... but you can back next time to top up. What a way to run a business... Must be the only one that doesn't care that people will leave as they cannot take money from a customer. But as I said it falls on deaf ears and no one cares. No need to reply to this post as all you say is the same rubbish as before.
