I just wonder this issue.
here are two cases of APN settings -EXAMPLE A and EXAMPLE B
EXAMPLE A
EXAMPLE B
I have just checked other threads, websites, etc, and some descriptions about "MMS without mobile data enabled", and I wondered.
Here is an interesting thread. According to it, we can send/receive MMS even when mobile data is disabled on some customised environment (not pure Android) such as MIUI, HTC, Sony, but we cannot send/receive MMS when mobile data is disabled on pure Android or Samsung Galaxy series.
I really wonder we must turn on mobile data toggles on APN settings EXAMPLE A. If APN setting is like EXAMPLE B, it may be true that we must turn on mobile data toggle in order to send/receive MMS.
On previous Synbian OS (Nokia), jailbreaked iOS (Apple), Windows Mobile, and fearture phones, we can send/receive MMS without mobile data toggle switch enabled. Why cannot only Android do the same if it is true that mobile data toggle must be swtiched on just for MMS.
There is another problem related to battery consumption. If we must always turn on mobile data toggle, the battery consumption will increase so rapidly, due to other background data tnansaction than MMS. The "packet filtering for MMS only" is vital and indispensable feature in terms of saving battery consumption, which is normal on any other mobile OS.
It is so easy to say on "APS Setting EXAMPLE B", "We must turn on mobile data toggle when sending/receiving MMS"
What I want to know is which case is correct on "APN settings EXAMPLE A"
Case 1:
Even on pure Android (nexus, etc), we must turn on mobile data toggle when sending/receiving MMS,regardless of SAMSUNG or Non-SAMSUNG handsets. MMS without mobile data enabled is only available on some manufacturer's customised Android handsets such as HTC and SONY.
Case 2:
Even on pure Android (nexus, etc), MMS without mobile data enabled is available as long we use any handsets except SAMSUNG.
It is just bug on SAMSUNG handset that we must turn on mobile data toggle even when we send/receive MMS only.
Which is right answer ? - Case 1? or Case 2? oe else?
I would like to know your answer, opinion and experience as much as possible. Thank you for your co-operation in advance.
