In general, it is not possible to have two SIM cards with the same number, as each SIM card is assigned a unique International Mobile Subscriber Identity (IMSI). This IMSI acts as an identifier for your mobile network, and duplicate numbers can lead to conflicts and confusion in the system.
A Dual SIM Passive phone is capable of using two different SIM cards, but only one of them can be active at any time. That means that when one SIM card works, the other is unreachable. To use the second SIM card, you need to activate it manually, and the first SIM deactivates when you do that.
If the phone you're switching to is from the same carrier or it's unlocked, you shouldn't need a new SIM. But if you're switching from one carrier to another, you'll need a SIM card for your new carrier.
And as you may have guessed, no phone number in your phone means no calling or texting. Losing these capabilities is only temporary of course. Once you reinsert your SIM card in your phone and get your signal bars back, everything will return to normal and you won't lose any data or information.
An old SIM card can be re-used unless it's so old that it doesn't support some feature you'd now want. And only the same operator that originally issued the card would take it in their network. A phone number is a separate thing from the SIM card. The phone number is controlled in the operator's systems.
Most of the time, it's impossible to have two phones with one phone number assigned by a traditional phone company. Of course, you can set up forwarding, but is it the same Not usually, because call forwarding typically happens when the call goes unanswered on the first phone number.
Keeping work and home separate
Having two SIM cards lets you keep calls and messages for two numbers separate. So you can give out your numbers to the appropriate people. Depending on the phone you can set it to prompt which number to call out on every time, or have defaults.
Dual SIM smartphones only have one antenna, so they have to switch between SIM1 and SIM2. If one SIM slot is empty all actions related to that slot are simply. As the phone already scans all cellular towers nearby an empty SIM2 slot should not cause any battery usage.
Yes, you can switch SIM cards between phones as long as they are compatible with the same carrier network. Your SIM card should also be compatible with the new phone in terms of size (micro, nano, and standard size).
Does taking out your SIM card delete everything The short answer is: nope. The shorter answer is: no.
No. SIM cards do not store data.
SIM cards go through an aging period after deactivation. After that period elapses, they cannot be reactivated.
When Can You Reuse A SIM Card You can reuse some SIM Cards after activation while others get “burned” or placed on temporary hold for activation. The table below details whether you will need to purchase a new SIM card or if you can reuse the old one.
With two phones, business owners believe that it's the easiest way to separate personal and business communications, ensuring that their professional conversations are kept secure and private. Two phones also enable business owners to easily switch between work-related calls and personal calls.
Yes, it is possible, although not recommended, because there is no guarantee that the two mobiles will work properly with a cloned SIM. They may not be able to register both on the network, randomly receive calls, and the mobile data service may not work.
ADVANTAGE: You can widen your network. If you've got two SIM cards following two different networks, you're looking at almost no coverage gaps. If you live in an area that has poor coverage no matter the network, or you enjoy traveling to remote locations, this is great for those who hate dropped calls and who doesn't
Your second SIM means you get two entirely separate bills. DISADVANTAGE: You might have to transfer it. Dual-SIM android cell phones are mostly designed international in nations like Chinese suppliers, because that's where they became popular.
If your iPhone supports dual SIM, you can use 2 phone numbers on 1 device. This is useful if you have a phone number for business calls and one for private calls, for example. Dual SIM can be used with a nanoSIM card and an eSIM.
Data that SIM cards contain include user identity, location and phone number, network authorization data, personal security keys, contact lists and stored text messages. SIM cards allow a mobile user to use this data and the features that come with them.
The biggest risk you take removing and inserting the SIM when the phone is on is a static discharge that could damage the phone and/or the SIM. It's unlikely, but there is a non-zero probability that you could damage something.
Changing your SIM card doesn't mean you'll lose your data. Your contacts, app, music, photos, and other data not stored on the SIM card will remain accessible. The only data that will be deleted is your old SIM card account information. Your Apple ID and iPhone settings are not affected.
In summary, when you put your SIM card in another phone, the only data that will be transferred is your own phone number and possibly a few text messages and contacts saved on the SIM card. The rest of your data, including photos, videos, and other files, will remain on your old phone.
Not unless you're creating clothing or jewelry from them. SIM cards go through an aging period after deactivation. After that period elapses, they cannot be reactivated.
Some mobile carriers allow you to use your number with multiple devices. With these services, you can forward incoming calls automatically to all your devices, including your phone, smartwatch, or tablet.
