Apple's mobile phone can't send MMS, but there is always an exclamation point. What happened?

If MMS cannot be sent, there may be the following problems.

1.

Which carrier's SIM card do you use?

/

Youxin

card

? Is it U-SIM?

or

User identification card

There is something wrong with this card.

? If you are a Unicom card, I suggest you go to the business hall and spend tens of dollars to buy that kind of iPhone exclusive. "

, bare card

. By the way, digression

There is a popular saying here.

:"

The world's first fool

Apple comes with a mobile card.

"

2.

I have encountered this situation before, and it was later found that it was due to improper operation when cutting cards.

Much better after changing the card.

But when the mobile card is placed on Apple, there is already a signal circle problem.

In the past, we bought bare metal in China Unicom or we could get the signal circle for free during the contract period.

. Besides, mobile 3G is not as powerful as Unicom.

I heard that mobile phones will launch 4G networks.

3.

Is your Iphone MMS set correctly?

? The three operators set up MMS in different ways.

. The correct answer should be whether these English inputs match your carrier card.

4.

Apple's mobile phone system is W-CDMA.

For the time being, only Unicom fully supports the three operators.

In other words, only Unicom is W-CDMA for the time being.

Welcome to continue asking questions.
