Having researched all of these new VOIP over mobile upstarts, it is obvious they will have issues if you take the time to understand what they are promoting. I learned the hard way that most are using the optional GSM smart phone optional data plans which will cost user up to $40 extra on top of your required existing plan.
Each of these VOIP over mobile offers promote savings, yet I saw no savings, and in some cases, the optional VOIP service cost more than I was paying. Here are the catches to look for. They promote using WiFi to state the expected savings, but unless you live in a hotel or airport, how often are most going to be within a WiFi hotspot zone of 100 feet? Most will not, so the savings promoted is purely hype based on unrealistic examples.
Now look at the real problem with using VOIP over mobile. First, you have to have a GSM smart phone. Second, you have to choose optional data plan which cost me $40. extra on top of my existing plan, and if you do not have a GSM plan from TMobile or AT&T, you have to switch to access a GSM data network which VOIP application is using. Simply put, you will have to spend a lot of money, even more if you are under contract with another non GSM carrier, so before you fall for any of the VOIP over mobile plans, do you due diligence as I have over past several months since these plans have hit market.
I did find a plan which was perfect for my situation, and it is not a VOIP over mobile plan, it is a new technology called Cellular Over Internet Protocol, COIP, so learn the difference as I have and you won't fall for the hype of VOIP over mobile. COIP puts a dial tone on any cell phone, not just GSM with optional data plans, in fact, you don't need any optional cost plans as you can use any carrier, not just TMobile or AT&T as with others. Here is the best part, if you travel internationally as I do, you can save up to 90% over traditional wireless mobile plans, so again, do your own due diligence before signing any contract with any service.
1ButtonToWiFi is the only one who can offer COIP as the technology is patented. COIP works will all cellular plans, and on all cellular phones, anywhere in the world, not limited access like the VOIP over mobile offers, so if you travel, or are located in countries not offering low cost wireless plans, then COIP is perfect for you. You can call anywhere in the world from anywhere in the world while avoiding costly roaming charges and poor quality connections.
And if the above is not enough reason to do you own due diligence, 1ButtonToWiFi also offers optional dual SIM multi-band 1Phone which is similar to iPhone but equipped with WiFi band, growing WiMax band as well as GSM and COIP network access for an even greater potential of savings. Simply put, 1ButtonToWiFi offers the perfect solution to save money on all wireless calls from their mobile phones.
There is even another strategy to save money, your current plan can be downsized to basic service for under $40., and if you have a plan of friends and family, circle of freinds which offer a select few frequently called numbers you add to list which are free calls, you simply program your COIP access number to list and all your calls are going to go through COIP network for a fraction of cost of overlimit charges of .40 a minute most carriers charge for overage. Your savings are dependent on your calling pattern, so compare closely to get the best value.
I am an affiliate with 1ButtonWiFi which was offering VOIP service alone, but now with both VOIP-COIP offering, you can save on your home or business calling as well for even more savings and now all users can become affiliates as well at no extra cost. Let anyone listen to your cell phone dial tone and they will be interested, try it, you own wireless service can be completely offset with viral passive effort sharing this technology with others, so watch the free video to better understand your options and you too will come to same conclusion I did, 1ButtonToWiFi is the best money saving money making solution of all.
