Receiving the network ID in a delivery receipt (DLR) in SMPP.
- Delivery Receipts
You need to include tag length value (TLV) 0x1421 with a value of 0x031 in your message request (submit_sm). As a result, the delivery receipt (deliver_sm) will return:
- TLV 0x1402 for the network ID (MCCMNC format).
- TLV 0x1422 and 0x1423 - These contain strings with the price and remaining balance.
