That's quite strange, CMGR response should have an intermediate response
prefixed by +CMGR: prior to the OK. Your modem is just weird ;)

What the stock AT modem driver does is reads the message and deletes it right
away. Somehow your modem says 'sure' to the read request without actually
reading the message. Maybe the firmware is just too slow or oFono is too fast,
or maybe this modem needs extra special magic.
