Most other folks use these things, but I don't want to be bothered by installations, extra equipment, or other gymnastics to use the service.
I have used
Web callback - Low Rates on Quality International Calling for Call Back Service for about 10 years or so, and it suits my needs. Why?
It is a call-back service. I use any computer with an internet connection to go to their website. I enter the telephone number where I want to receive the call, and the telephone number I want to call, anywhere in the world. They have a delay feature so that I can even receive the call anytime in the next hour. My phone rings, I pick it up, and in a few seconds, it rings and the other end picks up the call. I use the same telephone and lines as if I were using Jodetel or Orange.
No set-up fees, no extra equipment, no software installations, I don't have to pay a deposit, and my credit card is billed once a month, (or when my bill hits US$50) on the same day of the month for that month's calls. The statements for the past three months are all online so I can even use it to look up a number if I can't remember it. I print out the statements to get reimbursed for my business calls. They also have a conference call feature which I have used in the past, at equal rates.
I think the current rate from the DR to the states is $0.102 per minute. My phone bill is rarely over $25 a month. I have travelled extensively on business in the past, and have never wanted to be bothered dragging a laptop with me in my travels. I can use anyone else's computer or an internet cafe to make my calls, and I get the bill for the call, so no problem.
I know that BestNetCall now offers many other services, but I can't be bothered. I know this service, and it does what I need it to do, wherever in this world that I find myself. I am a technophobe, and don't even own a cellphone, so you can take my words with a grain of salt.
