There are lots of prepaid phone companies out there that brags about their low cost per minute rates just like SpeedyPin, but the truth is these companies have the most fees, it goes something like this a cheaper price per minute comes with higher costs.
After trying SpeedyPin, I noticed that that all charges are incurred from calls that were made, so I tried to purchase $5.00 US phone cards and finish it within just a week to save money, and it worked, I haven't been charged a weekly maintenance fee at the same time taking advantage of the low cost per minute rates. While there are other product lines that Speedypin offers; these are much higher quality phone cards that consist of call per minute rates and with the least amount of fees or let's just say reasonable enough.
Tackling about the consistency of speedypin while on calls, I can say thumbs up on their calling system, I haven't experienced any dropping of calls during important business conversation with my clients and also while calling my relatives.
One of the best things about Speedypin is they offer 100% guarantee on all kinds of purchase, I've tried a lot of prepaid companies that Promises the same with speedypin but on my dismay most of them are not reliable, and actually there are only few names that offers these kinds of guarantee in which they really should.
Speedypin also has excellent cost free customer support, polite and patient that will answer your concerns and handle every cases in priority, the only problem is that they doesn't operate 24/7, I have called them before when I experienced loss of minutes so I have no doubt with it, they gave me the compensation they promise within 48 hrs.
Also you won't need to worry when making online transaction with Speedypin, they are very serious in terms of security, I haven't heard any kind of problem regarding security of their consumers, and I guess they won't be operating this long from 1997 up to now if they have flaws with it. So overall I highly recommend SpeedyPin to my fellow consumers out there, take my word I've trusted this company since 2006 and they never had destroyed this trust of mine.
