What is a SIM card & What is eSIM?
Before diving deep into this topic, it is important to first know the difference between a traditional SIM card and an eSIM.
The term SIM card is an acronym for Subscriber Identity Module, which is a small, removable card that is inserted into a mobile phone or another cellular-enabled device. A SIM card contains a unique identification number that identifies the user to the network, allowing them to make calls, send messages, and use data services. The data stored on your SIM card only includes your user identity, location and phone number, network authorization data, personal security keys, a few contacts and text messages.
eSIM stands for Embedded SIM, which is a digital SIM that is embedded within the device and not a physical card that you can remove from your phone. Most of the devices that have been released in the last five years come with an eSIM option. The eSIM can be activated by scanning a QR code or by downloading an eSIM profile from the carrier, and it can be used on multiple devices with the same account. Also it can be transferred remotely without taking out physical SIM cards.
If I put my sim card in another phone, what will happen?
As mentioned earlier, your SIM card only stores your own number and a few of your contact information, some text messages, and a few other details your carrier may need to identify you on their network. Most SIM cards have space ranging from 8KB to 256KB, which is way too small to store any significant amount of data. Technically, most SIM cards can only hold up to 250 contacts.
Before the smartphone era, users would always be prompted to save their contacts on the phone’s storage every time their SIM cards got full. With advancements in technology, saving contacts is no longer a problem. Contacts can now be saved on the cloud, including Google Drive and iCloud, allowing users to seamlessly sync contacts between their devices. With such technologies, it has become uncommon for people to save contacts on their SIM cards.
Besides your carrier information, contacts and a few text messages, no other data is stored on your SIM card. Its memory capacity is not big enough to store a high-resolution photo captured on the modern smartphone. So, when you put your SIM card in another phone, it will only come with your number and a few contacts and maybe some messages. The rest of the data will remain on the old phone device.
Besides transferring your contacts, here are a few other things you need to know before switching your SIM card from one phone to another;
- Compatibility: Make sure the new phone is compatible with the carrier’s network and supports the same type or size of SIM card (nano, micro, or standard) as your current phone.
- Activation: If the new phone is not already activated on the carrier’s network, you may need to follow the activation process, which may sometimes involve contacting your carrier or going through an online activation process.
- Potential charges: Depending on your carrier and plan, there may be charges associated with switching devices or activating a new SIM card. Be sure to check with your carrier before making any changes.
When do I have to take my SIM card out?
Some of the common situations that will require you to take out your SIM from your phone include the following;
- When your SIM card goes wrong
Sending and receiving emails with no attachments requires about 10KB to 50KB per email, depending on If your SIM card is functioning normally, you may need to take it out and troubleshoot the issue. This could include cleaning the SIM card or SIM card slot, checking for physical damage, or contacting your carrier for a replacement SIM card. In some cases, the SIM card may need to be removed and reinserted to reset the connection. - When you want a new phone / new carrier
Browsing the web for one hour takes about 20MB to 100MB, depending on the amount of multimedia cIf you plan to upgrade or switch to a new phone or carrier, you may need to remove your SIM from your current phone and insert it into the new phone or activate a new SIM card provided by your new carrier. This process typically involves contacting your carrier to transfer your service and phone number to the new device. - When you travel abroad
When you travel abroad, you may need to swap your current SIM card with a local SIM to avoid roaming charges. Many carriers offer international roaming plans, but these can be expensive, so using a local SIM card may be a more cost-effective option. Be sure to check with your carrier to ensure that your phone is unlocked and compatible with the local network before purchasing a new SIM card.

My name is Dan. I had what I thought was a trusted friend take my sim card from my phone and put it in his phone.
Since then I’ve seen my name come up on other people’s phones and different sites. I’ve also noticed that money has come up missing from my account.. I know that I can’t do anything about it legally. It’s a lesson well learned. Very sad when this person will face his maker.
Hi Dan,
I’m sorry to hear that you’ve had a negative experience with your SIM card. It’s important to keep in mind that when you insert your SIM card into another phone, it transfers all of the data associated with that SIM card, especially your phone number, to the new device. Additionally, any unauthorized access to your SIM card could potentially lead to fraudulent activities.
To avoid situations like this in the future, we recommend that you never let anyone else use your SIM card or have access to it. If you need to switch phones, it’s best to transfer your SIM card to your new device yourself.
In terms of the unauthorized access you’ve experienced, it’s important to contact your mobile carrier and report any fraudulent activities immediately. They can help you take appropriate measures to protect your account and prevent further losses.

Hi,
my storage on my iphone was at capacity & drastically slowing its function. i joined iCloud & now the storage section has plenty of space, telling me how much i have left on the cloud. if i take out my sim to travel, & put a new sim in my phone, will all my data be stored on the phone again causing it to slow down?
im happy to not have access to photos but clearly want them in the long run. i just need my phone to work efficiently while travelling.
how can i resolve this issue?
thanks
Hi Trak,
Taking out your SIM card and putting in a new one won’t cause your phone to slow down, and your pictures will still be stored in iCloud.
In terms of your photos, you can keep them in iCloud and access them from any device, regardless of which SIM card is in your iPhone. To ensure that your photos are backed up to iCloud, please make sure that you have turned on the iCloud Photos feature on your iPhone. This will automatically upload your photos to iCloud and make them available on all of your Apple devices. If you’re worried about using up data while traveling, turn off iCloud Drive and only use it when you have Wi-Fi. To help your iPhone run efficiently, close unused apps and disable unnecessary features.
I hope this information is helpful to you. Please feel free to reach out if you have any further questions or concerns.

My old phone Samsung phone has a lot of information on it but has no service I play a lot of games and have not yet got a new cash app card or a PayPal card because it was stolen can I put the SIM card in this phone and will it give me the information of my money thanks so much Kimberly O’Neal
Hi Kimberly,
I understand your concern about accessing information related to your cash app and PayPal on your old Samsung phone. However, it’s important to note that simply switching the SIM card to another phone won’t automatically give you access to the financial information stored on your apps.
To access your cash app and PayPal accounts, you typically need to log in with your credentials on the respective apps. If your old phone still functions and you can install these apps, you may be able to log in and access your account information.
If your concern is about security or if your old phone is compromised, I recommend contacting the customer support of cash app and PayPal immediately. They can provide guidance on securing your accounts, changing passwords, and taking necessary precautions.
Remember to prioritize the security of your financial information. If you have any specific concerns or questions about the process, feel free to reach out to the customer support of the respective apps or let me know if you need further assistance.
