Yes. See the following FAQ: http://virginmobileusa.custhelp.com/app/answers/detail/a_id/895

Don't top up is the easiest way. There's no contract so you can come and go as you please

Just talked with a sales rep, and the plan is "totaly Unlimited" for data use.

5.5GB Gigabytes

no need to add money once you already have the unlimited web, plan will cover everything

All of Virgin Mobile's beyond talk plans have unlimited data, but once it goes past 2.5 GB at 3G speeds, it will be throttled. This means that you can continue to use data (surf the web, email, apps, etc) except the speed will be slower.

I believe you have mad a misconception. The 2.5 GB is a data cap for heavy data users. You see, everyone can get an unlimited data plan. However, when a user exceeds 2.5 GB of data, VM throttles the data speeds for their account. They can still keep using data but, it will remain throttled until the next month when the cap is renewed.

Tough crowd here. Virgin Mobile answered your question in the FAQs:

Reduced data speed on Beyond Talk plan Q&A

Q. When and how will data speed reduction affect my Beyond Talk Plan?
A. Starting March 23rd, 2012, if you use over 2.5GB of data during your monthly cycle, your data speeds may be reduced to 256kbps or below for the rest of that monthly plan cycle. During this time, you may experience slower page loads and file downloads, and lags in streaming media. Data speeds will return to normal as soon as your next plan month starts. If you'd rather not wait for your new month to start, you can restart your plan immediately through My Account.

Q. How will I know if I hit 2.5GB?
A. If you reach 2.5GB of data during your monthly cycle, your data speeds may be reduced to 256 kbps or below for the rest of that monthly plan cycle. If your data speeds are reduced for the rest of your plan month, you will receive a text message notifying you of this change. If you are susceptible to data speed reduction, you can check how much data you've used at any time during the month by logging into My Account, and checking Data & Web history.

Q. How much data is 2.5GB?
A. To give you an idea, it's about 400,000 mobile internet page views, about 90,000(!) emails (without attachments), 91 hours of streaming music, or 20 hours of video clips.

Q. I have a HTC EVO V™ 4G and I purchased Mobile Hotspot access. Will I still experience data speed reduction when my overall data usage reaches 2.5GB?
A. No. Purchasing the Mobile Hotspot feature will give you an extra 1GB of full speed. Connected devices, as well as the HTC EVO V™ 4G, will not experience a reduction in throughput speeds until your overall combined monthly 3G and 4G data usage from phone and hotspot usage. Once 3.5GB of data is consumed during the monthly cycle, data speeds may be reduced to 256 kbps or below for the rest of that monthly plan cycle. If your data speeds are reduced for the rest of the plan month, you will receive a text message notifying you of this change.

Your answer is to restart your plan immediately if you've hit the threshold.

I beleive I saw on the tv add that there was unlmited talk mobile to mobile?? (Any mobile to any other carrier too) And that the anytime minutes was for land lines calls only?? I have not switched because I want to be totally clear on this. I think VM is competing with Boost and Metro PCS?? If this is so, this plan suites me fine. otherwise I am going to Boost or PCS.

No sorry :( VM does not do mobile to mobile so even if you are talking to another VM user you are stiill using your 300 minutes

Just called customer service, and was told that even with "Beyond Talk" plan, you still need to pay for international texting. The rates are different to different countries.

per the terms and conditions as of 7/7/11:
international text messages: 15¢ to send and 15¢ to receive if you have selected a Beyond Talk Plan; 20¢ to send and 10¢ to receive with all other service plans.

Click 'Find a Store' at the top of this page for nearby stores.

You can buy them almost anywhere, your local, CVS, Wallgreens, 7-Eleven, Walmart, Whatever. Online is also great, You can get them without tax online, and like 11 cents cheaper, Hope this helps.

I wish they would work internationally. My LG Flare just said "searching for signal" in Denmark and Italy last summer (2009). It's a big hassle when traveling. Getting an overseas phone over there for just 2-3 weeks seems impractical.

no, the money that you will add on the acct will still remain on the acct if you will not use it.

no ur rate will stay the same unless u change it!
