The data top-up package was a bit too expensive.
Prepaidzero's delivery of my new sim to my paris hotel was prompt. the service worked flawlessly across france, switzerland and greek isles. data performance was excellent too.
The response of the emails is great.
The delivery speed at least for America is terrible, I wasn't able to use the product.
At first i had a good experience even though i wasn't able to use the sim card. the people behind the emails were very useful and kind by sending me another one to europe, which i didn't receive anyways. and when i asked if they would send me a refund they didn't answer. i'm going to email again to see if they can refund me as i'm already in my home country and im' able to return the sim card that arrived late to my home.
is there an easy way to check how much data is used/left?
There were moments during our stay in france that we had some problem to get connected..
Easy Activation; Pricing
Simple installation process; worked well in prc (even facebook, but only via the website not with any of the apps accessing fb); speet was much lower than with original chinese sims in same region.
Easy to use
I used prepaidzero to obtain a sim card which works in switzerland. although a bit pricy (local providers in switzerland were even more expensive) my experience was great. the sim card arrived after 1 or 2 days in my mailbox. the instructions were easy to follow and the internet quality was good.
They deliver what they promise.
Find cheaper solutions now the high roaming fees are not allowed anymore. Extend the period in which the sim card is valid.
Very good. fast delivery.
Ok to order from home.
Get agreements with telecom companies with better coverage.
We had problems with the t-mobile sim card during our stay in us. we were driving through rural areal where t-mobile coverage was non-existing. on t-mobile coverage map it seemed like there was coverage, but when investigating closer we saw that their provided coverage was through partners like at&t which were present everywhere. the bad thing was that t-mobile didn't allow prepaid cards to roam through partners. i will not recommend use of prepaid t-mobile sim cards in rural areas of us.
