Does Sierra Wireless modules (Q26, SL6087, SL80xx) properly send RP-SM-MEMORY-AVAILABLE to the network after deleting SMSes from a full SIM-card?
This question has come up after comparing to various cell-phones, what happens if an SMS is sent to the module (or cell phone) when the SIM-card (or other storage area) is full, and an SMS is sent.
On the sending side I get a report saying that the SMS can’t be delivered right away.
If I then delete SMSes on the cell phone, the SMS is delivered almost right away.
If I delete SMSes on Q26/SL6087/SL80xx however, I have to wait at least 10 minutes before the SMS is delivered.
10 minutes is the SMSC default retry time obviously, but this discrepancy seems to indicate that the SiWi modules does not notify the network that it can receive new SMSes.
This can also be noticed when the SMS is send while module or cell phone is turned off.
On cell phone, the SMS tends to get delivered right away when it logs in to the network, but SiWi modules have to wait for the SMSC to retry normally…
Any guidance from Sierra or anyone else that knows more would be welcome.
Does anyone know if cell phones usually send an RP-SM-MEMORY-AVAILABLE to the network during startup?
