[ベトナム][MOBILE]MobiFone 3Gのデータ通信情報（定額プランあり）

ベトナムの携帯通信キャリア第一位のMobiFoneが3Gを正式にスタートしましたが、エリアはまだまだ狭いです。
ハノイ市内でも穴だらけです。

さて、MobiFoneのサイトには3Gの説明があるのですが、ベトナム語Only。
http://mobifone3g.com.vn/index.aspx?s=internet

また、色々な方からベトナムのデータ通信についてお問い合わせがあったのですが、私もまじめに調べていなかったので、心を入れ替えて（笑）調べてみました。

とはいっても、テケトーに必要と思われる情報を英訳（Google翻訳を利用）しただけ。
まあ、だいたいの意味はわかりますね。

まあ、つらつら翻訳した英語をコピペしただけですが、まとめると、
私はすでにGPRSアクティベートをしていたので、999宛てのCAIDAT_DATAではエラーとなったので、この部分はかっとばして、
M50という定額プランを申し込むために、

999　宛てにSMSで
DK DATA M50

を送信。
すると確認メッセージ（ベトナム語）が返ってくるので、

999 宛てにSMSで
Y

を送信したところ、無事にM50プラン適用となりました。

プランの確認は、
999　宛てにSMSで
KT DATA
と送信すると確認できました。

7.2Mの3GのSurf30という無制限定額プランに使用かとおもったのですが、2つのSIMとも残高が300,000vndを切っていたのでした(^^;;;
また、3Gのエリアがまだ狭いことからSurf30のプランは不必要ですね。（費用対効果が得られない）
