  • Most SIM cards are compatible with Samsung mobile phones.

Option 1

First, remove the SIM card and gently wipe it, preferably using a microfiber or soft cloth. Put it back in its original location and see if it works. The process should restore your mobile functionality within seconds.

Option 2

If option 1 doesn’t restore mobile functionality, you still have the option of replacing the SIM card. It could cost you, but it’s a better alternative than replacing a motherboard. Never replace a motherboard unless you have everything stored on an SD Card.

Even better, you can return the phone with a refurbished type if you are on a strict budget. It is also better if you can’t afford to repair the old one.

Option 3

The last option is to eject your SIM card out of your device and insert it on another device while you exchange the SIM cards. It will quickly help you realize whether the problem is your SIM card or the mobile phone.

If the other SIM card works on your device, your SIM card could be the issue. However, if the other SIM card doesn’t function, then your Samsung mobile phone is the problem.

Can you use an iPhone SIM Card in a Samsung Galaxy S9?

The two SIM cards are compatible, and you can comfortably use any Samsung SIM card in any mobile phone. The only restrictions could be the physical sizes of the SIM cards for different models. In such cases, you will have to order the specific SIM card for your model.

For instance, iPhone 5 and higher models come with a Nano SIM, and you will have to manually reduce your SIM card size to ensure it fits perfectly. Another catch is when your former SIM card is locked to a specific network, which may result in incompatibility.

Still, you can contact the phone company that provided the mobile phone and request a network unlock code. Sometimes, you can order at a smaller fee to get it. Either way, it is cheaper than purchasing a new smartphone because of the network locks.

Does changing a 3G Samsung SIM card to 4G increase internet speed?

The 4G network offers better internet speeds than the 3G type. If your mobile network provider supports a 4G internet connection, shifting from 3G to 4G will boost your internet and browsing speeds.

It will be a better option, especially if you want to increase the internet speed on your Samsung smartphone. On the other hand, if your location is limited to a 3G internet connection, you are good at retaining the 3G speeds since there will be no notable internet speeds on your device.

How to Unlock a Samsung SIM Card

There’s no direct connection between Samsung and SIM cards. Usually, a network provider will be responsible for handling SIM cards, while Samsung will deal with phones. Unlocking a locked SIM card will require you to talk to the carrier.

However, you can unlock the phone if you fulfil your carrier’s network requirements. For instance, you need an active account to benefit from their services. Mobile network operators provide every SIM card with a Personal Identification Number (PIN) and a PUK. It would be best if you used the PIN to unlock the SIM card and even changed it to a new PIN.

If you lack the PIN, you will always be provided with a card with the PIN. Otherwise, contact your mobile network provider for the PIN. You can also talk to your carrier if you need help unlocking a Samsung mobile SIM regional code. If you accidentally lost a SIM card number, here’s how to obtain it.

How to Obtain a SIM Card Number from a Samsung Smartphone

The procedure is relatively easy, provided your Samsung smartphones are physically within reach. To do this, pick up the phone and call on another number. Your SIM card number will automatically display on the other phone’s screen, and you can note it down.

The scenario is slightly different if you lost your phone without a SIM card but would like to return it. Let’s check it out.

Can you Hack Your SIM Card on Samsung?

Hacking SIM cards is possible across all devices through SIM cloning, and Samsung is no exception. Usually, the entire process involves producing a duplicate carbon copy of your SIM card without your knowledge.

The complete information in your original SIM card will be transferred to a secondary SIM card when the entire process is complete. It will include call logs, transaction data, and other details saved on your original SIM card.

Your Samsung mobile phone will either use any of the two networks: CDMA or GSM. In a CDMA, your SIM card may be hacked by altering your phone’s Electronic Serial Number (ESN) using software, which is then transferred to the telecommunication company to endorse any other phone on the same network.

If you’re using a GSM network on your Samsung mobile phone, it will have an International Mobile Equipment Identity (IMEI) instead of an ESN. The hacker will have to target this number to create a duplicate copy of what’s on your original SIM card. Please note that not all SIM cards are susceptible to easy hacking.

There are two main types of SIM cards – COMP 128 v2 and COMP 128 v1. COMP 128 v1 is the most popular and prone to cloning by hackers. On the other hand, COMP 128 v2 is a complex type with better features, such as a better 3G network and safe firmware, with a complicated design, making it a bit difficult to clone.

Does Samsung allow Bootloader Unlock?

Yes, you can use the bootloader unlock feature on your Samsung device. However, it also depends on your geographical location. This feature is only supported in some areas but checks on your device if it’s supported.

Enable the developer options in your phone’s settings to check if it can unlock your phone. But do not enable the feature and restart your phone because this may restore your phone to factory settings.

Final Word!

Samsung is a good model, but there’s no direct relation between the company and your SIM card. Although SIM cards are compatible, changing from 3G to 4G will enhance internet speeds. Maintain your PIN and PUK to unlock your SIM card and install the tracking apps on your Samsung mobile phone to track any suspicious activity like hacking attempts.
