^^Yes you can. Use any tool like CDMA workshop to make it "RUIM only" and you are good to go.

have modems for sale 598u , prithiv modems too.. pm me for more details,
Ok just contacted BSNL EVDO in-charge and I am told that one cannot convert SIM based to Non-SIM based. Meaning if I have Prithvi Modem which is SIM Based then I cannot program it on non-sim based modem like ZTE or Sierra. I was also told that if I had the old ZTE modem then I could have transferred that account to the new Sierra but SIM to Non SIM is not possible. Is it true? Also with regards ESN number I was told that if I simply give my new modem ESN then the account could be changed and the new ESN would show up in their systems. Hence, like I have been telling earlier there is no need to change the ESN at our end. Simply telling them to change at their end would help and you could keep the correct ESN and not fall into any legal issues. I am told I need to buy a new EVDO connection and tell them that I need it for Non SIM based modem and then once account is activated tell them the modem ESN and have it programmed at a local BSNL EVDO center and the modem could begin working.
Has anyone who has got SIM transferred their account to a Non-SIM based without need to change number? I was told that series of SIM and Non SIM are different and hence nothing can be done. Any help?

Can someone help me with this problem - www.techenclave.com/community/threads/cannot-setup-usb-modem-in-linux-help.148841/
the answers are
Yes officially you cannot convert RUIM to non sim based
Unofficially you can make a RUIM based connection to work on non SIM i.e ESN based modems
You can officially transfer esn of BSNL ZTE to Sierra or any other .BUT WHO IS GOING TO PROGRAM IT ? If you think BSNL guys will do it you are in for a long ride . They only use ZTE PST for programming esn based device .
"Simply telling them to change at their end would help and you could keep the correct ESN and not fall into any legal issues" - yes it works but who programs it and most important of all SOME EXCHNAGES dont allow foreign esns so ....
You will not get a new connection without a device .They will release the mobile number on a esn or in RUIM .Try it out
I got a new connection on Sierra esn only when the JTO of CDMA MAIN SWITCHING CENTRE of my city confirmed to BSNL sales guy that he will program the device . Good luck to you on that .
For getting a new ESN based connection people get a ZTE based device activate it and then give esn of Serra which is legal . Thats what all max have done .
The main reason why people have to change esn is because of BSNL apathy . If they start helping /programming why go the other way
Hi
You say
As per their website
You say
How can I do that? Because the BSNL official told me both work on different principles and hence not possible to configure a SIM number on a non-sim based modem. If its possible, then how?
This is wrong. You can get. When I went to buy a new connection I was asked - do you have your own modem or you wish to buy from BSNL. If we have our own device they ask if its RUIM Based or non RUIM based. Even BSNL website mentions that you can get your own device and not necessary to buy from BSNL.
As per their website
So thats very much possible and I did confirm with the BSNL official that its possible.
When you take new connection on your own device you have to give the esn number for NON SIM based connection . Leave own device , if you try this out on BSNL ZTE device then also you have to give the esn . Why dont you try it out . No one will give you a new connection + a new phone number without giving any esn number on a NON SIM based device
Whatever BSNL crap you are quoting it works same way . If you have own device and RUIM based they give you a RIUM . If you have own device esn based then you give esn number on new connection form
Ok what I am asking is your answer
If you know how I can keep the SIM number same and yet connect using the non SIM based EVDO modem let me know how. Thanks
How can I make the non sim one work with the SIM number? BSNL says its not at all possible because if you have ESN based number / device then what they do is add the ESN to their database and only then your connection work. While incase of SIM/RUIM based the authentication format is different because you could change devices by simply removing the RUIM from one device and placing it in another device.
If you know how I can keep the SIM number same and yet connect using the non SIM based EVDO modem let me know how. Thanks
It was already answered /discussed earlier which involves changing esn which you have deemed as illegal . Read the thread for more answers

BSNL already have all the non-RUIM devices ESN listed in their database which they sell. I requested them to put my Sierra ESN in their database but they said it's quite impossible to modify it.
From past 9days I'm unable to recharge on EVDO, and therefore unable to use my EVDO connection. Anyone else facing the same issue in the EAST Zone? They said that there is some maintenance going on, but maintenance going for 10 days??? It's very weird.

Hi @kuduku
Well like I have been telling the BSNL official told me that SIM based do not work on the principle of ESN and hence not possible to change at their end. We need to take a Non_SIM based connection from them and then they could add my device ESN in to their database and make it work. What the official mentioned is that in case of SIM based just by removing the SIM from one device to another one could use the connection. I tried using it on another EVDO Based device of another company - so BSNL would not have any ESN in their database. Yet as soon as I added the SIM to that device, the connection began working. Hence SIM based EVDO works on a principle similar to GSM Mobiles, you can simply remove and add SIM to another device yet your mobile would work. It would have nothing to do with the ESN.
@hayabusa_ryu
Well you could try online recharge via paytm. That should work.

@prtk : Maybe the BSNL official himself isn't clear. 
But to make things clear, any CDMA device work based on the MEID/ESN. In case of RUIM, all these details are stored in the RUIM which is why you can freely change devices by simply inserting the RUIM, just like a GSM SIM.
Now, in case of non-RUIM based devices, all the information like ESN etc are stored on the device itself.
As many others have done it earlier, you could simply get an RUIM, make the ESN of the Sierra same as the RUIM (Yes the RUIM has an ESN of its own), destroy the RUIM and program the Sierra as required and it will work.
If you do not want to change the ESN at all, then you must get the ESN of the Sierra registered in BSNL database, and as @kuduku mentioned, this is not a simple task and unless you find a BSNL official knowledgeable/willing enough to do it, it can't be done.
If you take a new connection and opt to use your own non-RUIM device, you need to provide its ESN. And unless this ES N is already registered in BSNL's system, activation will fail. If the BSNL official mentioned that he can get the ESN added, specifically ask him whether he can get a foreign non-ZTE ESN added. He might be thinking you have a BSNL non-RUIM device which will not have any issue as the ESN is already registered with BSNL.

@varkey - I donot completely agree with you. I will go back to the BSNL official and get clarification. I had taken my device and he definitely said that if its a non sim based number only then can it be used for non sim based connection. If I have a SIM based connection, first I need to buy a new non SIM based connection from them and they would definitely configure the device for me. He called his superior and told the device details and I was told if I buy a Non sim based connection then he could definitely make it working!
I am not sure if ESN has anything to do with it because I tried adding my SIM on another EVDO device (which has SIM Slot and not of BSNL - but another company) and my connection worked fine. Even the BSNL official mentioned that the SIM(RUIM) and non RUIM based connections work on separate principles and incase it was non SIM based connection all they have to do is along with my non SIM number add an ESN to their database for that number and it would start working within max of 1 day. He confirmed it can be easily done.
Any other option with me?

You need to first try to understand how the whole CDMA thing works.
I can personally guarantee you that if you have a RUIM based connection now, and a Sierra 59x device, then you can get it running without applying for a new connection or any change from BSNL's side. I am sure everyone here except you will agree to that. Both RUIM and non-RUIM based connections works exactly the same, its only the location of the ESN and other data which is different, which makes one somewhat fixed to a device while the other can be interchanged between devices.
ESN has got everything to do with it, period! I suppose you didn't even read my previous reply properly.
Having said the above, if BSNL is ready to add a foreign ESN and activate the connection by all means go for it, but don't just assume its impossible any other way.

@varkey - thanks for the update. But as suggested earlier too I wont change ESN from my end as its not legal. And like I mentioned earlier BSNL official says its impossible to tie a RUIM based number to a specific ESN from their end. They say its only possible if I have non RUIM based connection. The official specifically mentioned that had I got the old ZTE based connection which does not have RUIM then they could easily have transferred / activated it on this device.

@prtk : Don't confuse yourself. Both are ESN/MEID (newer) based (You cannot register to a CDMA network without a valid ESN/MEID), you may however take it as RUIM and non-RUIM based devices.
The part about not able to convert from a RUIM connection to a non-RUIM connection strictly depends on BSNL's capability. Reliance CDMA for instance, you can easily switch both ways without any issue.
If you can get the Sierra's ESN registered then you are very fortunate as in majority of the areas, they simply do not do it, probably cause the person in-charge doesn't know how to do it!

@varkey - update! I have a friend who uses the old ZTE connection, so today we went to the BSNL Office and from there we were asked to go to BSNL EVDO department where all EVDO matters are handled. So we finally reached there and its a bit away from the main office. So the person incharge took the number (that he uses to recharge) of ZTE and then checked the ESN of the new modem. He then said wait for some time. Finally he came back and said in some time the modem will begin working as he has updated the ESN in the database against the friends connection. Now I just connected and it works fine without any issue. My friend is happy now that he has REV.A connectivity as earlier the ZTE was having REV.0 connectivity. So I have now given the modem to him as its working fine for him
Coming back to the discussion - Hence, I again state - like the official told me - its not possible to tie a RUIM number to a specific ESN and hence its not possible to transfer / configure RUIM based to non RUIM based. He said if its non RUIM based its easy to tie a specific ESN to that number and once that matches the modem would start working. He said that now the old ZTE wont work as the ESN has been removed against that number and thats not working.
I am not sure if someone who has got a RUIM based connection has managed to configure it on a non-ruim based modem and if one has successfully done so I would like to know how because as per my meeting and discussion its theoretically not possible!

Everything is possible if only your local BSNL people co-operate with you. they can add RUIM's IMSI and Sierra's ESN to the database. it is simple as that. and connection should start working.
