    Benefits of using dual SIM iPhone

    Continue reading to learn the most potent reasons to use dual SIM iPhones if you’re unsure whether you need them.

    1. Maintain one iPhone

    You no longer need to carry two phones everywhere you go if you have a personal and professional number on a single iPhone with dual SIMs. Also, you may just top up one number and access cellular data on your iPhone without needing to pay anything extra to maintain your other number.  

    2. Better network coverage

    Staying connected even during carrier outages or service gaps is another reason why you should use a dual SIM iPhone. If you have an iPhone with two SIMs, you can switch to another SIM if one of your telcos has technical issues or poor signals. You will have twice the possibilities for cell reception.

    3. Grab amazing carrier deals

    Due to rising competition, all telcos are trying to hold their customer base. So, if one telco provides better packs for making calls, and another offers cheaper data packs, you can use a dual SIM iPhone to access both deals.

    4. Separate work and personal lives

    It can be complicated to distinguish between phone bills for business and personal usage if you use only one number for both. Hence, having a dual SIM iPhone is helpful to differentiate between the bills to get reimbursed.

    Many users are reluctant to relinquish their personal phone numbers when moving to a business handset. However, if your company lends you a dual SIM iPhone, you can keep using your private number with a work number.

    5. Traveling benefits

    If you are traveling abroad, purchasing a local SIM card is often far more affordable than needing to pay roaming fees for the destination nation to make calls. Hence, using an iPhone with dual SIM is highly recommended over a single SIM in such cases to significantly increase your travel savings.

    Apart from that, you may take advantage of exclusive discounts on a local SIM. Contacting local companies or persons using a local SIM card is much simpler and offers greater network strength than your international SIM.

    6. More storage for contacts

    Most physical nano-SIM cards come with up to 256 kilobytes of onboard storage capacity that can be used to store your contacts and texts. Hence, using dual SIM cards on your iPhone can allow you to carry twice as much data, like your contacts and texts, without syncing anything with iCloud.

    7. Enable or disable a SIM with ease

    If you have dual SIMs in your iPhone, out of which one is strictly used when you’re traveling, you may want to temporarily disable your other SIM case or eSIM to prevent roaming charges. Here’s how you can do this with ease:

    1. Go to SettingsCellular.
    2. Select a SIM you want to enable or disable.
    3. Toggle on or off Turn On This Line.

      Enable or disable a SIM with ease

    8. Setting preferred SIM for specific people

    Having two SIMs makes it easy to manage your personal and professional contacts. Also, you can set different ringtones for both SIM cards, allowing you to distinguish between your professional and personal calls easily.

    In case you want a certain SIM/number to be used every time you call a specific contact by default, you can also do that on your iPhone with ease.

    1. Open a contact in the Phone or Contacts app on your iPhone.
    2. Tap the last-used option above the contact’s name.
    3. Select a SIM you want to use when calling the contact → Tap Done.
