Travel Technology - International Network for Smartphone Data Roaming??

Is there a company that has coordinated with communications service providers (CSP) in countries across the globe to agree to one or several rate plans for smartphone data roaming so individuals could have seamless access to data roaming as they travel internationally?

Clearly there would be complexities based on the data communications protocals of ones smartphone, but the world seems to be honing in one only a few 3G and 4G protocols now.

While there are some with two or more than one country, the AT&T International Data Plan is the only one I've found that has worked in many countries (140). It is available to people from all carriers.

Here are the countries included in the data plan:

Is anyone aware of others?

Verizon, AT&T and Sprint all have / had International Data Plans.

Verizon has a Global Unlimited Data plan, called "Global E-mail" for $64.99/mo, for unlimited data.
It is no longer available to the general consumer though, now it is only for Business or Government accounts.

Someone mentioned online that he managed to convince ( after a lot of effort ) Verizon to allow him to have the plan for his individual account. But he is in the military so it might have helped.

In some other countries, Hutchison offers "3 Like Home" that allows their customers to use oversea "3" branded networks at their domestic calling / texting / data rate.

I have the same plan from ATT, but it may be closed. I am unlimited on my iPhone (data side only) anywhere in the world. I have an account with Line2 (a pay service similar to Google Voice) that lets me send and receive text messages world wide for free using the datafeed, make VOIP calls, or reprogram the number on the the fly to my prepaid or roaming SIM dejour.

Vodafone has its passport and Eurotraveller plans for business travelers. O2 has a Euro Traveller program. Truphone has a business traveller plan which covers Europe.

That AT&T package looks good compared to what would have been on offer a couple of years ago. Where I live my PCCW service offers some decent international tariffs - i think in the main network operators have stopped ripping people off so much.

I wouldn't bother with any of these dedicated 'traveller' networks - ive found the service to be patchy when ive used them in the past.

They've made substantial reductions in price. They first dropped the price of the bundles by 75% in the summer of 2011, then another 40% drop this year. So the price for blocks of data is now 15% of what it was a couple of years ago. But the a-la-carte pricing is still ridiculously high, at $20/MB if you have no int'l data plan.

Verizon's replacement to the above mentioned $64.99 data plan (that I used to have and they suckered out of me, dammit) is a $25 per 100MB plan.

Fortunately, on a Blackberry, data is compressed so it doesn't use all that much as long as you stay away from streaming media.

For my use, the Verizon international data plan ($25/100 MB) is better than the ATT Plan. And Verizon gives me the corporate discount on top, making it much more palatable for occasional short-trip international travel. Where possible, I get a local SIM and use it in an unlocked int'l MiFi.

There apps like Onavo which compress data or iPhone and I think Android as well.

Re her apps like Onavo which compress data or iPhone and I think Android as well.

Can anyone comment on how apps like Onavo and Snappli work? Do I simply download them to my phone and they run in the background compressing data as I use it or do I have to do all web searches through that app? Does it slow down anything on the phone or run down the battery at all?

PC Mag has a good review of it here, but yes, everything compressed has to run through their servers. You don't do anything different, it runs in the background and takes care of where stuff goes for you.

Onavo Works by routing all Internet-related actions through its servers, where data is compressed before being sent to your device. This is similar to what RIM does with its BlackBerry devices, using server-side compression to reduce the total amount of data transmitted. The Opera Mini Web browser also uses server-side data compression, although it only tackles activity happening within its own app. Onavo works across apps, including Safari, Mail, and so forth.
