What is the reason why Apple 7 SMS function can't take pictures?

Hello, Mr. Mobile Phone at your service.

According to your question, if the other party is also using Apple devices, you can send pictures directly with iMessage.

If it is an Android device, it needs to be set before sending. The method is as follows:

First, open the phone's settings and click General.

Locate the internal network and click Open.

Look for cellular data in the network again.

Click Open.

Set inside

APN (CMWAP)-MMSC (mmsc.monternet.com)-MMS agent (10. 0. 0. 172)- Maximum message capacity of MMS (307200).

(usually

10240 is enough).

Once set, you can send MMS, that is, SMS with photos.

I hope my answer can help you, and I wish you a happy life!

(Hope to adopt, thank you! )
