PrepaidZero

Bought an unlimited data card for the USA last month. The card was delivered to my home address within 2 days. As soon as I arrived in Pennsylvania I changed the sim-cards and the PrepaidZero card was immediately operational; connection to the internet without having to go through difficult, timeconsuming things. Also during my stay in worked perfect, no problems whatsoever!

Ordered two T-Mobile SIMs which were labeled as usable in US, Canada and Mexico for a trip through Canada. Both SIMs were activated according to the instructions, only one received a phone number.
Neither SIMcard had ANY data whatsoever. Support told us once to 'enable roaming' and simply mailed a PDF with the instructions we already had, to no avail of course. Requested a refund but all communication was ignored.
The phone is never answered. Our tickets were closed without any confirmation or even a reply. Bad, bad service and a waste of money, effectively inditinguishable from a scam.

I recently went to London from US. Bought the prepaidzero UK+Europe 12GB data SIM card and added cash on the card for talk/text. I was told it was compatible with my galaxy s5. When I put the sim card in my phone, my phone just said it didn't recognize the card and wouldn't do anything even through wifi. I bought it mostly for data so I could use GPS but thank goodness my daughter had a phone that worked. I couldn't contact prepaidzero until I returned as my phone wouldn't do anything and was told since I was already back there was nothing they could do. After many emails, I did receive a refund for the cash balance on my card for talk/text. It was a very frustrating experience during my vacation. I wouldn't recommend.

Daughter had school trip to Italy from Australia. I unfortunately did not think about ordering a card sooner. At about 14 days out from leaving we telephoned and also corresponded by email to the wonderful helpful staff at Prepaid Zero. We were told it should take 8 days for the card to arrive.
Unfortunate this was over the Christmas period and by the post marks it had left Europe very promptly but unfortunately in arrived 1 day too late for my daughters departure. I was worried I might never see my 86 euro again for this data and phone prepaid plan. After contacting them, I sent it back with all details. All ended very well.

I was going to USA for a week and bought a SIM card from PrepaidZero in order to keep up with my mail and manage work remotely. I suspected something wasn't right when I got the card and the instructions said I had to enable roaming!? The entire idea was to NOT have to use roaming. As it turns out the card I got was actually Israeli! And when I used it in my Samsung Galaxy S7 I never got better than H+ (no 3g or 4g or lte) which just wasn't working. I ended up paying for a roaming deal with my normal carrier instead and got 4G right away.
Not worth the gamble.

We were given UK numbers - not Italy ones. When I asked about that they told me it was free to call and text UK numbers so our travel group could communicate with each other. I was only able to ever text one of them. Sometimes I would try to text or call and money would be deducted from my account. I could only complete calls to Italian numbers a couple of times in a month. I had thirty euros credit and was not able to use most of it and they would not refund it when I asked. I followed the instructions they gave me when i emailed to find out what was going on. My brother finally just gave up and got a regular Italy SIM card. Should have done that from the start. It's not that hard. Don't waste your money with this company.

Don't do business with this company! My SIM was extremely slow and despite several emails I did not get any reaction! Their phone number reaches an answering machine and is never answered and never returned despite the messages I left...

I usually buy sim cards after I arrive in a foreign country and It usually it talks a while before the card is activated. I was attracted to prepaidzero because it works in more than one country and is supposedly active immediately on arrival. Mine didn't work. Through email prepaid zero gave me the number of the carrier to resolve my problem.
The carrier said the sim card I had been given was incompatible with mobile phones. It is supposed to be used in a broadband device. I have spent a lot of time trying to figure out what was wrong. I am not happy. I have asked prepaid zero for a refund. I will write another review to describe how that goes. I am sure there are many happy customers. I am not one of them.
