Where to find packet on vhf/uhf In the US, most packet activity is found on the 2 meter band:
2 meters: Baud rate is typically 1200. he most common frequencies are 144.93, 145.01, 145.03, 145.05, 145.07, 145.09 and 145.53 MHz, but you may find it anywhere between 144.90-145.10 and between 145.50-145.80. The baud rate used is 1200.
1.25 meters (220 band): most packet heard in this band will be "backbone" traffic between network nodes and BBSs. It will not be an access band for users.
70 cm (440 band): The packet allocation for the band (mixed mode segment) is 432.10-432.30 and 432.40-433.00. Packet should not be used below 432.00. By local option, packet could also be used from 442.000 to 445.950 and 446.100 to 448.000. Baud rate may be 9600 or 1200.
Note: some packet heard in this band may be "backbone" traffic between network nodes and BBSs. If so, there will be no user access to nodes or BBBs on the frequency. https://www.soundcardpacket.org/8frequencies.aspx#:~:text=In%20the%20US%2C%20most%20packet,145.10%20and%20between%20145.50%2D145.80.

Sending Messages: From: https://smsgte.org/ug-sending-messages/ Sending from APRS to SMS
Sample message generated using Kenwood TM-D710 To send a message from an APRS station, simply address your message to SMSGTE with the following format:
@
Example:
To: SMSGTE @6135551234 No cell coverage here, ping me on radio When the message is delivered to the destination SMS number (usually a cell phone), the message will appear as follows:
@VR4XXX-10 No cell coverage here, ping me on radio Of course, the callsign at the start of the message will be your callsign. The originating number will be the gateway’s number for your region.
Sending from SMS to APRS
To send a message from SMS to an APRS station, address your message to the gateway number with the following format:
@
Example:
To: 2015551234 @VE3OTB-10 Did you forget your cellphone? The message delivered to the APRS station will appear as follows:
6135551234 Did you forget your cellphone? Please note that the gateway telephone numbers have not been published here to prevent spam messages being sent into the APRS network. You will learn the gateway’s number when you send your first message from APRS to SMS.
Conversations initiated by an SMS user will only be permitted to callsigns that have previously used SMSGTE. This has been implemented both to mitigate the potential for SPAM and to simplify the parsing of SMS messages received by SMSGTE. Messages are stored for 24 hours.
Request Delivery Confirmation A user may request delivery confirmation by adding a question mark (?) to the end of the callsign or SMS number. If the message is destined for APRS, a confirmation message will be sent to the SMS user only once an Ack was received on APRS. If the message is destined for SMS, a confirmation message will be sent when SMSGTE confirmatin from the SMS service. Confirmation is intended to verify that the message was delivered via the APRS network. Confirmation requests work with raw phone numbers and aliases. Use the following format:
From APRS:
@
@6135551212? My car broke down, can you come help me? @mywife? My car broke down and my cell is dead. From SMS:
@
@VE3OTB-9? Is your radio on?
