I was considering using Viber and Vonage while in the US (Viber for contacts who only use Viber for VoIP).
Is there anything particularly compelling about using Google Voice (over Vonage)?
It all depends I guess.
They all do the same thing basically. With Vonage you can call anybody for free (so long as you have 3G or wifi). I think the deal is still on for 3000 minutes free/month.
GV is really US centric but it does allow you to have one number in the US that you can direct to any other. So if you travel frequently to the US and end up with different prepaid SIM cards each time, then you don't need to worry about it - just always provide your GV number and direct calls to the current cellphone number you are using.
It means for your local or US friends/rels who don't use Viber, they can reach you with one number.
I find GV handy in NZ since it means I can send SMS to my daughter in the US for free. She prefers SMS since all her US friends use text and so she only has one place to look for messages and to send them (even though she has a smartphone). And she is on an unlimited text plan.dickytim: Please note that I could not find prepaid sim cards at Walmart, Target, Walgreens etc.
Don't bank on being able to get one there.
If you have transport, or are in a large city it wouldn't be an issue, but I had a lot of trouble in Vegas finding a place to get a AT&T sim card. I ended up at the Fashion Mall next to Caesars where there was a mobile phone accessory shop, but they were a rip off!
I have never purchased the ATT card in a store - always bought it online with ATT and had it delivered. But I have been able to find TMO cards in the malls. They usually have a booth in the mall (not a store) where you can buy phones and cards. The last time, before they officially supported the iPhone, they even sold me a regular SIM and punched it out for my wife's iPhone!
Anyway if you plan things properly it's easier to buy the SIM from home and have it delivered to your hotel/friend's house.
And if you can't buy the SIM card at Walmart, you can certainly buy the $30/month plan (unlimited data, text and 100 minutes online)
and have it e-mailed to you.
But interestingly TMO won't sell that to you.
We’re going to the West Coast next month and have therefore been following this thread with interest. We’re planning to take an iPhone 4, 5 & iPad. Does anyone know if I’d be able to buy a nanosim for the iP5? I have a cutter for MicroSim so will pack that just in case.
TMO seem to be winning as far as I can see.
Going to set up GV too but I can’t seem to do that until I have a US number :(
