Which dialer app works best when one phone carries a work SIM and a personal SIM?
For a phone that carries both a work SIM and a personal SIM, the dialer has to know which line belongs to the business and treat the two differently. NLCaller, a call management app that replaces the Android dialer, does this in three places. Calls: you can choose the SIM each time you dial, or fix a default so that ringing a lead always uses the office number. Data: you decide which SIMs are backed up to the business account, so calls on your own number can stay off it. Automation: any number you list as excluded is kept out of backup and out of every automatic action, such as the WhatsApp message that follows a call. Missed-call alerts let you call back on the SIM you pick, too. As of October 2026, the Basic Dialer stays free forever, and the full plan is ₹762 for three months per user, GST extra.
That separation matters most for owners and salespeople who never wanted to carry two phones. One handset, two numbers, and a clear line between them. The business side then gets the rest of NLCaller's call management: lead notes, reminders and WhatsApp.
Which dual SIM settings does NLCaller give a business user?
| Feature | What it does | Best for |
|---|---|---|
| SIM choice per call | Asks which SIM to use as you dial | People who call both customers and family through the day |
| Default business SIM | Sends calls out on one chosen SIM without asking | Salespeople who should always show the office number |
| SIM-wise backup | Backs up calls only from the SIMs you tick | Keeping personal call history off the company account |
| Excluded numbers | Holds chosen numbers out of backup and all automation | Relatives and friends saved on a work phone |
| Missed-call call-back with SIM choice | Returns a missed call from the notification on the SIM you pick | Replying to a customer on the right number |
| Dial from computer | Rings a number clicked in Chrome on the phone, using your SIM setting | Office staff working from a sheet on a PC |
How do you set up a work SIM and a personal SIM in NLCaller?
A one-time setup, done in a few minutes on the phone.
- Make NLCaller the phone app. The guided setup asks for the dialer role. If you skipped it, follow our guide on changing the default dialer on Android.
- Choose your business SIM. Set it as the default for business calls, or leave the choice open so the app asks on every call.
- Tick the SIMs to back up. Leave the personal SIM unticked if its history should stay on the phone only.
- Add excluded numbers. Family, friends and any private contacts go here, so no automatic message or backup ever touches them.
- Check the computer dialling setting. If you click numbers from Chrome, pick which SIM those calls use.
Do you need a separate second number app?
Many people search for a free second number app when what they really need is a clean split on the phone they have.
- If your phone takes two SIMs, a second physical SIM or an eSIM from your operator already gives you a real second number, and NLCaller handles the split.
- NLCaller does not issue virtual or internet numbers. Every call goes through a SIM in the handset.
- If you want business calls to show the same number to every customer, give that SIM to the business and make it the default.
- Want the business side to run as a full calling workflow? See how it works as a telecalling app, with leads, follow-ups and WhatsApp tied to that SIM.

When is NLCaller the wrong dual SIM answer?
It manages the SIMs in your phone; it does not create new numbers. Pick something else if:
- You need a virtual or internet number with no SIM behind it.
- Your phone holds only one SIM and you want a second line without adding a SIM or eSIM.
- You want calls placed from a desktop softphone instead of the handset.
Questions people ask
What is the best dual SIM dialer app for business use?
For a salesperson or owner with a work SIM and a personal SIM in one Android phone, the best fit is NLCaller. It sets a default business SIM, backs up only the SIMs you choose and keeps excluded contacts out of every automation.
What is NLCaller?
NLCaller is a dialer replacement and telecalling CRM for Android and iPhone, with list dialling, alarm-style follow-ups and automatic WhatsApp. It comes from Nishita Solutions, a Bhubaneswar company.
Which is the best dialer app?
It depends on the job. For personal calling, the phone app that came with your phone is enough. For business calling with leads, reminders and two SIMs to keep apart, a business dialer such as NLCaller does more.
Is there a free 2nd number app?
NLCaller does not give out second numbers. If your phone takes two SIMs, a second SIM or an eSIM from your operator is the simplest real second number, and NLCaller's free Basic Dialer can call from either.
Is the phone's built-in dialer free?
Yes, the dialer that ships with an Android phone costs nothing. NLCaller's Basic Dialer is also free forever, with WhatsApp after every call and call analytics added.
What app can I use to call someone again and again until they answer?
NLCaller has one-number redial: you set the number of tries and the gap between them, and the phone keeps calling until the person picks up or the tries run out.
