Pros: as title

Cons: none

Pros: -Quick delivery (~10mins)
-Works fine once you figure out how to use
-Good for light users

Cons: -Instructions not clear, had to go to Q&A to find out that Virtual Gift Card number is actually the PIN
-Verify balance in the email delivery link doesn't work, thought the card was invalid.
-H2O recharge confirmation email doesn't tell you the recharge amount. Had to go to its website or use your phone to find out.

Other Thoughts: Don't understand why H2O doesn't provide an easy way to refill like this in its website.

Pros: Received code within 10 minutes.
No problems using code.

Cons: None.

Other Thoughts: Received code quickly and applied to my H2O account without issue.

Pros: Works great.

Cons: None.

Other Thoughts: $10.00 pin for three months and 200 minutes sent to your e-mail.

Pros: Worked as expected. I used it to activate a H2O SIM card. Everything is like a breeze. I entered its "Virtual Gift Card ID" as the "airtime PIN" on the online activation page.

Cons: None so far.

Pros: Works as expected: type in the code, the recharge shows up in my account.

Cons: None on the recharge card.

Pros: Best value currently available using AT&T network for those with GSM capable phones who are light to moderate users.

Cons: Occasional bad connections, but not too bad.

Pros: Convenient
Fast

Cons: Not sold on the H2O web site.

Other Thoughts: I don't know why H2O does not sell this on their site. Luckily NewEgg sells this, and I found it. I bought a new phone and SIM card. this is what needed to get them working.
