Yeah, by "basic GSM" I mean a common subset that is available regardless of 2G/3G/4G/5G, as in, you can still ping the mobile equipment to see which BTS it's connecting to. (And even if you don't get the TA with CDMA/OFDMA you still get signal strength and/or can force a downgrade if necessary, to get a rough location.)
I'm not sure if you're shadow banned or what, but every comment of yours I have encountered has been marked dead. I vouched for this and another one I saw elsewhere in the thread.
Made the account an hour ago, maybe that's why. Thanks for the heads up
Sorry about that; software filters are tuned more aggressively for new accounts. We've marked your account legit so it won't happen again.
