SmartBro ZTE MF637 HSUPA modem unlocking

Recent STF(search the forum) I found how to unlock my ZTE MF637 HSUPA 3g modem.

My intention is to look for MF627 unlocking technique for my SmartBro Plug It modem, I downloaded some apps and follow some instructions posted in some forums.

I did not succeed on MF627. Quite unhappy... I was thinking to put my next target my other modem which is model MF637 for unlocking. At first I'm afraid that it might brick the firmware, because there are some suggestions that it is only intended for MF627. Huhh... the hell...what I was thinking... and so I made up a choice to take the risk.

Before unlocking;

a. My Smartbro dashboard is installed and modem drivers, typical installation for SmartBro to work/connects.

b. Replace your Smartbro sim card (e.g. Globe or Sun SIM)

From one of the applications given to unlock MF627 is DC-Unlocker 2 Client v1.00.0460




1. Download the file DC-Unlocker 2 Client (dccrap.zip)
2. Unzip/Extract to any folder or to your desktop

Now Plug in your Smartbro modem with Globe or Sun SIM inserted on it.

3. run the dccrap.exe
4. Select Manufacturer = ZTE datacards
5. click "server"
6. Enter Username/Password of your choice then click "Check Login".
For me, I enter smartbro for both userb=name and password
7. Click on the the Magnify Glass icon to search your modem model automatically.
Dont need to Select model manually.

Just wait for the modem to sync, sometimes reading the datacard is slow.

8. Once your modem has been detected, Click "Unlocking" then UNLOCK it.

You will be then prompted unlocking successful!

Now, Open your Smartbro dashboard, it takes a while to sync in the modem.

From my experiment, I use Sun sim card. Once it catches the signal, you can notice it from the dashboard, signal .::| and the network name (SUN)

Then I configured my Network Settings to Sun Internet on my dashboard.
Name: Sun Wireless(any name of your choice)
Dial Number: *99#
APN: minternet

Set it to default.

Load up with i50 (24 hours unlimited) with 5 pesos regular load balance.

Then here it goes....


Now I wont have to use a strainer to catch that signal of Smart, because we are near to Sun cell site here in Laguna.
