Need help to configure Sierra 598u on BSNL EVDO. Urgent!

I want to say Thank you kuduku, cisco_tech and other forum members who started original thread for 595 u. This discussion thread help me out to understand configuration and other information related EVDO.
 
Is there a way to configure modem to latch only to Rev A and not Rev 0? I have both towers in range in my location and the modem keeps fluctuating between these two.

As matter of fact I have the same problem. For 5 seconds I get 3Mbps and next 5 secs nothing. It's annoying. Btw, I am using ZTE AC2766 now.
 
After a long time I opened the battery from the modem (Sierra 595U). I see that it has swollen a lot and I am scared thinking that it might booom! anytime soon. Feels like there is sponge inside.
Now from where can I get its new battery? Any chance here in India or even ebay.in?
 
But it is not connecting without battery. When I plug it in without battery, network is full but network strength becomes zero if I try to connect to internet.
 
I have got an spare OEM battery which is fairly new, without any swelling. Ready to sell it for 400 Rupees. Please let me know if you are interested

If nothing works, you please check if there is a RUIMSlot or not ZTEAC8700 has one under the cover and HuaweiEC1260 comes with a DUmy(False) card. Youhave to unlock it first via CDMAWorkshop Unlocking procedure: 1. select the comport in which it is connected, 2. click the Connect button to connect your device with CDMAWorkshopmodem by using the radio button of CDMAWorkshop , 3.After successfully connected your device click the read button to read the parameters of your connected device, 4.connect the , 5. Under Security tab,make sure that, it remains on default n_vread and write Put SPC as 000000(sixZeroes) after clicking the SPCButton select Send. it should show the following message as "SPCcorrect and phone unlocked", 6. Now on the other tab go to select,"RUIM if available put unlock code as0000 0000 on both and click write Now your Modem is unlocked to be used with any CDMA RUIM.
