I no longer receive notifications for text messages on my iPhone 4. How can I best troubleshoot this?
Thanks for the A2A.If you haven’t done so already, try restarting your iPhone.Also, tap Settings, then tap Notifications and scroll down until you find Messages. Tap it and check your notification settings. Also check to make sure Do Not Disturb is not turned on. (It is really easy to accidentally turn it on in Control Center). You can tell if Do Not Disturb is on if there is a moon at the top of the iPhone screen next to the location, bluetooth, and battery indicators.If none of that works, you could try doing a Factory Restore.That’s about all you can do short of taking it to an Apple Store or buying a new phone. (Hey, it’s an iPhone 4 — maybe its time.)
Can I send and receive texts if I turn off cellular data and Wi-Fi on my iPhone?
Certainly ‘Yes ‘ .SMS stands for Short Message Services .This one of the many Basic services just like telephony , call waiting etc which need to be provisioned for a stranded Mobile subscriber , so It doesn't Matter which Handset you are using , ( Iphone.. Andriod or any basich phone like Nokia 3310 )SMS falls under is non-voice basic services .So SMS service is pretty old and does not required the “Data” ( here data means data services enables eg. 2g ( edge/GPRS), 3 data, or 4G) or Wifi connection .I would say any mobile phone should support this basic service .Even if you are not talking your phone is constantly sending and receiving information through radio channels towards Base transceiver station ( BTS) eg, control channel.In GSM to enable SMS, there are some basic protocols such as SS7(Signaling System No.7) and SMPP(Short Message Peer to Peer Protocol).SS7 used between core elements. SMPP is used in IP domain.Below is the complete call flow with more details :-image src: rf wirelessSo as long as you have GSM signal you can send and recive sms.Now a days some operators have Wifi Calling service here you can still send and receive voice calls and legacy SMS if you are on coverage of only WiFi.interesting point here that SMS is transmitted via Mobile Application Part (MAP) of the SS7 protocol where the payload length limited by 1120 bits, which further limits the maximum size of txt message as 160 7-bit characters .Well it is also worth to mention that the new IM messaging apps like whatsapp, Viber , WeChat etc are killing legacy SMS service and rarely people use SMS .If you liked it please upvote!
What can you do when your iPhone won't send pictures?
You can try these two ways to fix iPhone won’t send pictures in text. iPhone indeed supports sending pictures via MMS or iMessages. If your iPhone won't send pictures in text, my guess is you don't have MMS enabled on your phone.1. Fix iPhone Won't Send Picture via MMS2. Fix iPhone Won't Send Picture via iMessage1. iMessage works when you have it enabled and the recipient is also using iMessage. This requires the recipient is also using an iPhone, iPad, iPod touch or a Mac. So, confirm this first.2. Check the Wi-Fi/Cellar network. Try to open a webpage in browser to check if the network works fine. Or you can reset network via Settings > General > Reset Network Settings.3. Restore your iPhone. If you can't send pics via messages still, you are advised to reset your iPhone to factory settings. Since factory reset will erase all data on your iPhone, please backup your device with iTunes or iCloud first.Then, connect your iPhone to computer with USB cable and open iTunes > Click "Restore iPhone ..." button in the summary panel when your iPhone shows up > Click "Restore" again to confirm your action. Then, iTunes will restore your iPhone to factory settings. When your iPhone restart, you can restore iPhone from iTunes backup or iCloud backup.4. If even the factory resetting cannot solve the problem, the issue may caused by the iMessage server itself. Since this is out of your control, you just need to wait the server to turn back to normal.Note: Before resetting your iPhone to factory setting, you should back up your existing data first, so you can restore the contents with the iPhone backup in your iTunes later.
Can an Android smartphone send/receive SMS texts via wifi?
The reason why Android smartphones can send or receive a text/call via wifi is because they follow 2 protocols : ToIP (Text over Internet Protocol) and VoIP (Voice over Internet Protocol). In case you’re wondering, these are the same protocols used by instant messaging services like WhatsApp.Wikipedia says that SMS is “text messaging service component of most telephone, World Wide Web, and mobile telephony systems.” Note the phrase World Wide Web - this basically entails that SMSs can be sent over the world wide web, which is essentially the internet. It is important to understand that it is the app that decides whether you can send your texts over the Internet, and not your phone itself. For example Android Messages, Google’s default messaging service, recently got the ability to send text messages over Wifi. Similarly Messages, Apples default messaging service, can also send iMessages to and from a large variety of devices, including Macs that traditionally do not have a telephony modem. How? Through WiFi, of course.Now I do not know the technical details of how exactly a text/call goes over the internet - you’re going to have to do your own research on that. Just know that it is in fact very much possible for (new) Android and iOS smartphones to send SMSs via WiFi.
Can a phone work without a SIM card? Why or why not?
Well...Let's go with a YES....a phone, that is: the device today known as a smartphone, which employs -in some occassions- a SIM card- can work without a SIM, providing that :If you want to use that device as a phone, cellular phone, then NO, it won't work. It requires the SIM card to be able to "enable" so to say, the actual phone number and then connect and identify itself to a cellular network and ultimately place and receive cellular phone calls.Now, it you want to use that very same device with or without a SIM card for:WiFi based Internet purposes (navigation, downloading pictures, movies, music)...Music listening.Movie / video watching.Pictures taking with the camera.Any internet based communications (hangouts, skype, etc. -WhatsApp may depend on having had, at least once, an operational SIM card tough-)Then your phone WILL perfectly work fine, as all this activities, (except perhaps for WhatsApp activation), do not require, nor depend on a SIM card and the functionality this SIM provides.
Why do my texts say sent but not delivered?
SMS messaging works in a chain. The message must be first sent to an aggregator, and messages can sometimes get delayed, especially if they are undergoing any sort of maintenance. Local towers and carriers may also experience technical difficulties which can result in the end-user not successfully receiving a message. If a message says "sent" that means that your job is done but that it may not have successfully reached the recipient. Though it may not be entirely relevant to a personal experience with texting, here is a blog that explains (in a nutshell) the process in which a text is delivered from a business such as AvidMobile, which is an application provider for text message marketing: SMS Aggregator: How it Works and Why You Should Care

What are push messages that I get in my smartphone and what is the difference between a normal message and a push message?
I think when you say “normal message” you mean an SMS / Text message, and the top differences between an SMS and a push-notification are below:SMS messages are sent to phone numbers…so as long as the sender has your phone number she can send you an SMS message. In contrast, push notifications can only be sent to people who have downloaded the sender’s mobile app and still have it installed.Push notifications these days can be pretty rich in it’s format — for example, you can embed images in the message (background typically); you can control/play different kind of notification sounds when they are delivered; you can put interaction buttons on them and more. In contrast, SMS — which actually stands for Short Message Service — is restricted primarily to simple text in its format.SMS messages don’t need you to have a “data plan” to receive them. Of course it depends on your telco provider and plan, but typically voice/sms are bundled together. In contrast, push notification requires a data plan (or WiFi connection) for you to receive themhope this helps
Can you send texts in airplane mode?
Putting your phone into airplane mode turns off all its antennae - cellular, wifi, bluetooth, GPS. At that point, you can't send or receive anything. But modern phones usually let you turn wifi back on while in airplane mode - after all, many airplanes have wifi.If you're in airplane mode, but have a wifi connection, you can send non-SMS texts over the wifi connection, using iMessage on an iPhone or various other messaging apps (WhatsApp, etc.) But you wouldn't be able to send a plain old SMS text to someone without the same apps.
