One sim customer service is very good One sim customer service is very good, no need to wait, just dial from your mobile to customer care, and within one minute you will receive a callback. All problems were listened to very carefully and they were resolved instantly. last 7 years I have been using this service in various countries whenever I travel. No need for a local country number to dial someone.

I gave 5 stars for the help we received from Gino I gave 5 stars for the help we received from Gino over the phone. He was very knowledgeable about how the SIM card functions and explained everything well. He made suggestions about data plans based on our specific circumstance and told us about how to get the most savings for texting etc. We haven't used the card yet so this 5 star review is only based on the great customer service that we received from Gino. Thanks!

ACTIVATION A bit of trouble activating - my own lack of experience - I did not include the oo before the number to use to confirm activation. Called the help number & spoke with Brian - quickly sorted me out

Can't Use Visa or PayPal I have used OneSim for a couple of years. Since day one I have not been able to use my credit cards (RBC Visa and Mastercard in Canada) to buy credits on the Sim account or even buy credits in the 1Simfund. So I have been using Paypal to make payments on their system. However it appears that they are no longer allowing Paypal so it's adios to OneSim. I've never had such a frustrating experience trying to give money to a vendor. UPDATE. After this review OneSim sent me an email explaining that my account information must match exactly what is input on their order system. I have spent hours with my bank trying to correct this and nothing works. I have not had this issue with other vendors in over 30 years of using my Visa cards. Very disappointed.

Excellent customer service Thank you to the customer service folks David and Andrew - good information and details on what is the correct sim card for my trip. Thanks also for expediting shipping. Well done OneSimCard.
