Problem connecting to operator "Swisscom"(a swiss mobile operator) about cloudhopper-smpp HOT 1 OPEN

I've successfully used this library together with Swisscom's "SMS LA (Large Account)", is this the offer you use?

Please check:

• That you're not exceeding the global client TCP connection count, it's fairly low (5 I believe)
• Not sure about this, but use only bind_transmitter and not bind_transciever if you're only sending messages
• Make sure the bind-request fills in the correct fields for both "username"/password (system_id/password)
• Make sure you ordered an SMPP interface (not UCP)
• Make sure that if, applicable, your IP addresses are whitelisted for the account you're using
• Read the "tiny letters" at the start of the documentation, rest appears copy-pasted from the regular SMPP specs.

And once you're past the bind, if you want to use non-UCS-2 encodings, make sure the encodings match what you're sending (verify if it's ISO-8859-1/ISO-8859-15 by sending a euro sign/currency-sign/cedilla e.g.) For me using ISO-8859-15 and setting submit_sm.data_encoding=0 allowed use of € (euro) correctly. I was never able to use GSM-03.38 directly.
