There could be a few reasons why your iPhone has no service. It could be due to a lack of coverage in the area, an issue with your service provider, or an issue with the iPhone itself.
In areas with poor coverage, your iPhone may not be able to locate a cellular tower that is providing the necessary signal. If this is the case, the best option may be to move to an area with better coverage.

Do SIM cards expire?
Yes, SIM cards do expire. A SIM card’s expiration date depends on the telecom company and the subscription plan; however, a SIM card typically expires after two years or after a certain amount of money is spent, whichever occurs first.
Once the SIM card expires, the phone number associated with it can be recycled and given to another customer. In general, telecom companies will provide an early warning before the SIM card expires. Some telecom companies allow customers to extend their SIM card expiration period.
If the customer does not renew, the SIM card’s services will be rendered inactive.
Can a SIM card get damaged?
Yes, SIM cards can get damaged. SIM cards are prone to scratches and other physical damage, which can render them unusable or make it difficult for them to connect to a mobile device. Water damage is also a potential risk for SIM cards, as some may not be water-resistant or waterproof.
Additionally, SIM cards can become damaged if stored improperly, especially if exposed to extreme temperatures or humid conditions. SIM cards can also be affected by static electricity, which can render them unusable or make them unreliable.
In order to prevent these kinds of damage, it’s important to store your SIM card in an environment that is not too hot, not too cold, and free of static electricity. Additionally, always keep your SIM card away from water.
Can you reactivate an expired SIM card?
Yes, it is possible to reactivate an expired SIM card. Depending on the cellular network provider, you may be able to restore the connection just by calling your provider or visiting their website. Also, in some cases, SIM cards are retrieved from the cellular network and re-registered with a new phone number from the network operator.
The process of reactivating your SIM card will differ depending on your provider. Generally, if you contact your provider and inform them that your SIM card has expired, they can help you reactivate it.
You may need to provide some personal information and pay an activation fee to the provider for reactivation. Additionally, it is possible that the provider may require that you purchase a new phone number.
It is also worth noting that in some cases, particularly with prepaid SIM cards, the expiration date may have passed without the card being deactivated. In this case, you may be able to continue using your SIM card with the same phone number and no additional steps are required.
Can I get new SIM card with same number?
Yes, you can get a new SIM card with the same number. This is possible if your current provider allows you to transfer (port) your number to the new SIM. In order to do this, you would need to contact your current provider and request that they port your number to the new SIM card.
They will then provide you with the necessary information and steps you will need to take in order to complete the process. Depending on your provider, you may be required to pay a fee to port your number.
Once the porting process is complete, your new SIM card with the same number will be activated and you can start using it.
How long does a SIM card last without recharge?
It really depends on the type of SIM card that you have, as well as how active it is. Generally, prepaid SIM cards will have an expiration date, often three to six months after activation, depending on the network provider.
After this date, the SIM card will no longer work, even if the card has not been used or a recharge has not been made. In most cases, staying on a recharge plan and topping up at least once each month will extend the life of the SIM card.
Postpaid SIM cards usually do not have expiration dates, but they may be deactivated if they remain inactive for too long. Inactive SIM cards may be deactivated after a few weeks or months, depending on the network provider.
To prevent this, it’s important to use the card and make at least one call or send one SMS each month, just to keep it active.
Why does my iPhone keep telling me no SIM card installed?
There are a few different reasons why your iPhone may be telling you that there is no SIM card installed.
The first possibility is that you may have either dislodged, damaged, or otherwise removed the SIM card from the device. This can happen if the SIM card tray has been tampered with, if a foreign object ends up inside the tray, or if the tray was not properly snapped shut after the SIM card was installed.
In this case, you would need to power off your iPhone, take out the SIM card, make sure it is undamaged and properly seated in the tray, and then reinstall it into the iPhone.
Another possibility is that the SIM card itself is faulty. If you’ve recently purchased a new SIM card, you may want to double check that it has been properly activated, as not all carriers will activate a SIM card automatically.
Otherwise, you may need to request a new SIM card from your wireless provider if there appears to be an issue with the original card.
Finally, there could be a software issue that is keeping your iPhone from recognizing the SIM card. A simple restart of the iPhone or a full reset may help fix this problem. If the issue persists, you may need to contact your iPhone service provider for further advice.
What can I use to clean SIM card?
If you want to clean your SIM card, you should use a soft brush, such as an old toothbrush, or a fine cloth. First, you should turn off your phone, then remove the SIM card from your device. Make sure that the metal contacts on the SIM card are not bent or broken.
Next, take your brush or cloth, and gently wipe away any dust, dirt, or residue from the metal contacts. You may need to use a small amount of water to remove any tougher build up. Once the contacts are all clean, simply dry them with a dry cloth or paper towel and re-insert the SIM into your phone.
What happens when you clear SIM data?
When you clear SIM data, the data stored on your SIM card is removed. This includes items such as contacts, texts, and multimedia messages, as well as settings saved by the carrier. Some carriers may also save data such as account information, subscription information, and carrier service settings.
When you clear SIM data, all of this saved information will be deleted. Additionally, any applications or services associated with your SIM card get removed. For example, if you have a prepaid SIM card associated with a specific data plan, then deleting the data will also likely result in losing access to that plan.
Clearing SIM data is useful for a variety of reasons, such as when you need to reset your SIM card, if your device isn’t working properly, or if you’re changing carriers.
