There are different methods to block text message sender on iPhone. I will show you one of them. Just follow the steps as below.

This works really well for blocking phone number on iPhone, like phone numbers from some unknown spammers, advertising companies and internet marketers bothering you with promotions and offers for products that are not at all related to your interest. These steps will block only those unknown callers that you choose to block. The detailed steps are as follows:
1. Go to the Messages app.
2. Tap on the target message from the spammer.
3. Choose "Details" on the top right hand corner and tap on it.
4. There will be phone icon and a letter "i" icon across from the number. Tap on the "i" icon.

5. Scroll down to the bottom of the page and then tap on "Block Contact".

Note: Once you press on Block Contact, the phone number that you just blocked won't be able to make phone calls, send text messages, or Facetime you.

Need to block a specific phone number from calling or texting your iPhone? It could be telemarketers, spam text messages, or that crank that won't stop calling and messaging. Apple's iOS does not have a built-in feature to block a phone number, but there are other solutions.

1. Your carrier might be able to block individual numbers. AT&T has an optional feature called Smart Limits for Wireless that runs $4.99 per month. One of the many functions is the capability to block up to 30 numbers from calling or texting your iPhone.

Verizon Wireless offers Spam Control for no additional charge. This feature can be found under My Services when logged into your account, and blocks up to 5 numbers from calling or texting.

2. Owners of jailbroken iPhones can install apps from the Cydia Store that will block phone numbers.iBlacklist is fully compatible with all iOS devices, iOS 5 and older firmware. For a one-time cost of $12, iBlacklist adds a plethora of useful features to your iPhone including the ability to block calls and texts from individual numbers.

MobileLog is currently in development and will be offered for sale to jailbroken iPhone owners soon. The app will also provide many enhancements to the stock calling app as well as number blocking.

3. Make sure you've registered your iPhone number with the National Do Not Call Registry. This will not stop texts, but it will require most telemarketers to stop calling your line within 31 days. Complaints can also be filed using the same website, and phone number registrations with the service never expire.

4. Assign a silent ringtone to the numbers you don't want to answer. This stops calls from bothering you, but texts will still sound an alert.

5. Another calling only solution are services such as TrapCall, which has plans starting at $4.95 per month. No iPhone app installation is required, and once you're signed up TrapCall will unmask blocked caller IDs and blacklist unwanted callers. More expensive plans can be purchased that offer more in-depth functions.

Call Block is a service provided by your phone carrier. For most providers you dial *60 (star 6 0) and follow the voice prompts. After you have blocked this number, you will not receive any more calls and it will not ring through from the number you blocked. The phone device itself does not have that capability. Only your service provider.

1.Make a call from that number to your number.

2.You will receive a missed call message.

3.You will see that number in the 'recent contacts'.

4.Click options.

5.In the pop up menu, come down and you will have a 'reject list' option.

6.Click and make sure you delete that number entry by pressing 'remove' in the options.
