Leading telecommunication firm Mobitel has recently introduced another exciting mobile broadband service, Unlimited 3.5G for US$50 a month. Despite its promotion says the package is unlimited, it also comes with a term of conditions or fair usage policy.

There are two different Cellcard 3.5G Data Cards, one is for single user ($30 for the device), and the other is WiFi Router ($100) for multiple users with speed up to 3.6Mbps and 7.2Mbps. The subscription plan is available for $5 daily (unlimited), $20 weekly, and $50 monthly. Mobile Internet users can use existing Cellcard to recharge their account credit, without having to visit Mobitel office.

Mobitel sends its promotion text message (SMS) to its Cellcard users:
“Get a USB data card for [$]30 with our 3.5G mobile broadband packages. Calll 812 for more info!”

Mobitel isn’t alone. Its competitors are doing quite well to grab market shares. Axiata’s Hello offers unlimited 3G broadband Internet for as low as $1 a day with average speed at 128kbps (kilobits per second) or $28 a month.

Potentially a hard-to-beat rival, Metfone has yet made it right as Vietnamese company hasn’t offered unlimited bandwidth for its Metfone USB 3G. But this will soon change since data-cap isn’t a favorite choice for many data-hunger users.

A user, Leang Ang, asked on an online forum about Cellcard’s unlimited mobile Internet promotion:
I am wondering if anyone is using the cellcard internet promotion 50$ a month. I went to the company and was told that they provide 40GB a month with a broadband speed up to 7mkps. I am not sure about this, because as you knew its promotion last time about the unlimited broadband. What about the actual speed? anybody here experience this?

And here’s a quick response from an existing user, Alfred Wilhelm Meier:
I use it since 14 days: traffic is unlimited and included in the 50 $ Option. Speed depends on the net and its quality, 3G is secured in most of PP area, but in rush hours the throughput gets slow. In rural places there is no 3 G; I was a couple of days ago in Kep; the USB modem worked, but in a slow mode. Alles Gute und bis bald!
