Howto collect MSISDN numbers

Dear openBSC users, This project sounds interesting and promising. I would like to collect MSISDN (mobile numbers) for people attending a fundraising gallery. Then I send them SMS (using the MSISDN list I made) with 5 bucks donation link. Of course I can run with a pen and paper and do that, but instead I would like to use technology to help me. Is this possible to do with openBSC? Or even other GNURadio modules? I am not interested in: using openBSC to make/receive phone calls nor IMSI and TMSI. Bands of interest are: 900/1800 GSM 2100 UMTS In case this is not possible using GNU Radio modules. Is there commercial solutions to do that?
