iPhone search services are usually caused by several common reasons. Solutions include 1. Check the signal coverage, move to a strong signal area, or use Wi-Fi to call; 2. Confirm that the flight mode is not enabled, turn off through the control center or settings; 3. Deal with SIM card problems, try to restart, reinsert or check the SIM card status; 4. Update the operator settings or reset the network settings to fix the software problem, and if it is invalid, contact the operator or Apple support.
Your iPhone might start searching for service due to a few common reasons—none of them are usually too serious, but they can be annoying. It could be something as simple as being in a low-signal area or something like a temporary glitch with your carrier settings.

Here's what typically causes this and how you can fix it.
1. Poor Network Coverage
This is the most straightforward reason. If you're in a basement, remote area, or surrounded by tall buildings, your iPhone may struggle to find a stable signal.

- Move closer to a window or go outside
- Check if others on the same carrier have the same issue
- Consider using Wi-Fi calling if available
Sometimes, even though you expect good coverage, towers might be down temporarily or overloaded—especially during events or bad weather.
2. Airplane Mode Was Successfully Turned On
It's easy to toggle Airplane Mode on without realizing it, especially if you use the Control Center often.

- Swipe down from the top-right corner (or up from the bottom on older models)
- Make sure the airplane icon isn't blue/active
- If it is, tap it off and wait a few seconds for cellular service to return
You can also go to Settings > Airplane Mode and double-check the switch there.
3. SIM Card Issues
If your iPhone can't detect the SIM card properly, it'll show "Searching..." instead of your carrier name.
Try these steps:
- Turn your phone off and back on
- Remove and reinsert the SIM card (use the proper tool!)
- Look for any visible damage or dirt on the SIM
If the problem happens after switching SIMs or traveling internationally, your carrier might need to update your account or unlock the device.
4. Carrier Settings or Software Problems
Sometimes, your iPhone just needs a refresh in how it talks to your carrier. This doesn't happen often, but when it does, restarting or updating can help.
Try:
- Restarting your iPhone
- Checking for carrier updates under Settings > General > About
- Resetting network settings (Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings)
Carrier updates are small files that tell your phone how to connect to the latest networks. If one is available, installing it can resolve service issues.
A few other things to consider: if you're traveling abroad, make sure roaming is enabled. Also, if your phone is unlocked and you switched carriers recently, the old carrier profile might still be active.
Basically that's it. Most of the time, a quick restart or SIM check solves the issue—but if not, contacting your carrier or Apple support is the next step.

Determining the depreciation value of iPhone requires multiple factors and comparing different platforms. 2. The first choice is Apple's official replacement plan, which has a simple and transparent process, but the final valuation must be based on the actual condition of the equipment. 3. Third-party websites such as Gazelle, Swappa, etc. may provide higher quotations, but you need to pay attention to describing the real situation and avoiding the charging trap. 4. The core factors affecting value include model and storage capacity, equipment status, operator lock status, etc. Small problems may also affect the quotation. 5. If you pursue higher returns, you can choose to sell privately, but you need to weigh the time cost and transaction risks.
