Why are business calls not answered in Korea?
Because unknown and unfamiliar numbers are screened heavily, often automatically. Calling from the mobile number the customer already has is the practical response, which is what a SIM-based dialer does: the call goes out on the seller own number rather than a virtual one. RMDialer adds the record, opening the customer as the phone rings and saving the outcome in two taps, in a Korean interface.

What businesses say about RMDialer
Real businesses, real numbers: how owners and sales teams across India and 12+ countries use RMDialer every day.
-
“We needed an auto dialer app that works on our own MTN and Airtel lines, not a call centre subscription in dollars. RMDialer runs on the phones my agents already have, dials the enquiry list, and the WhatsApp follow-up goes out after every call. Works even when the network drops and syncs later.”
Grace Okafor Managing director · Travel agency Lagos, Nigeria -
“Telecaller app for Android that my staff actually use. Enquiry list is assigned to each telecaller, the auto dialer calls it from their own SIM, and test ride bookings come to me live. Punjabi interface for the girls at the desk. Price is honest, everything included, no per-user surprises.”
Harpreet Singh Owner · Two-wheeler showroom Ludhiana -
“Most CRM tools here are built for a desk. Our brokers sell from their phones, so a telecalling CRM inside the dialer made sense. Leads from Facebook ads land in the app, the auto dialer calls them, and the tripping schedule rings each broker. Tagalog interface, own Globe SIM, no VoIP number for clients to distrust.”
Maria Santos Operations lead · Real estate brokerage Manila, Philippines -
“Multilingual team, so a CRM with English, Malay and Chinese interfaces mattered. The auto dialer runs our launch lists on the agents' own Maxis SIMs and the manager sees every call and remark live. We compared three cloud call centre tools; this cost a fraction and needed no virtual numbers.”
Daniel Tan Sales director · Property developer Kuala Lumpur, Malaysia -
“Bulk calling app was the search that brought me here. 300 dealer numbers pasted from Excel, SIM 2 selected, 6 second gap, and my two boys finished the list in a day and a half. Busy numbers got retried by itself. Earlier same list used to take a week with a notebook.”
Amit Patel Director · Textile trading Surat -
“Best CRM dialer we have used for a small team. Call comes in, the lead card is already on screen with the last remark, and the status change is two taps. Only complaint: the web CRM export could use more filters. Otherwise our 6 person sales team lives in it.”
Neha Srivastava Founder · Digital marketing agency Lucknow

Mobile sales CRM and dialer for South Korea: what changes and what does not
Korean consumers screen unknown numbers with unusual thoroughness, assisted by widely used call-identification apps, and the practical result is that a large share of outbound calls from unfamiliar numbers are never heard. That makes the origin of the call a more important variable than its content, which is an uncomfortable conclusion for platforms built around pools of virtual numbers.
Dialing from the seller own mobile sidesteps the problem rather than trying to defeat it, and pairs naturally with the second requirement: knowing who is calling you before you answer. Because the app replaces the phone dialer, inbound calls arrive with the customer name, status and last remark already on screen, which in a relationship-heavy market is the difference between continuing a conversation and starting one.
Everything else is the same product you can read about across this site: the auto dialer app, the CRM dialer where the record opens as the phone rings, the automatic WhatsApp after a call, and the telecalling CRM the owner watches in any browser. Pricing is the same worldwide at a free 3-day trial, then one plan with every feature included.
Questions from businesses in South Korea
Updated on
Does the app work in Korean?
Yes, Korean is a shipped app language, with Chinese, Japanese, Vietnamese and English also available, set per person on their own phone.
Why does calling from a SIM matter in Korea?
Because unfamiliar numbers are screened aggressively, frequently by the phone itself. A call from the seller own mobile number, which the customer may already have saved, is answered where an unknown virtual number is silently rejected.
Does it handle inbound calls too?
Yes. Because the app is the phone dialer, an incoming call opens with the customer name, status and last remark on screen, so the conversation starts with context rather than a question.
Can I use an auto dialer with a local SIM in the UAE, Nigeria or the Philippines?
Yes. The dialer places ordinary SIM calls from the phone, so it works on Etisalat and du, MTN and Airtel, Globe and Smart, or any other operator, at the operator's normal call rates. Follow the local rules on marketing calls (for example the UAE's and the Philippines' consent requirements) exactly as you would for manual calls.
What is the difference between a power dialer and a predictive dialer?
A power dialer calls one number at a time for one agent and waits for that call to end, so every answered call has a person ready. A predictive dialer calls several numbers at once and connects the ones that answer to whichever agent is free, which needs a call-centre server and causes dropped "silent" calls. Mobile auto dialers like RMDialer are power dialers on a SIM.
Is an auto dialer legal in India?
Yes, for calling your own leads and customers. An auto dialer is only a faster way to place normal SIM calls, so the same rules apply as for manual calls: do not call numbers registered on the national DND list with promotional offers, honour opt-outs, and follow TRAI's rules for commercial communication. Calls to people who enquired with you, existing customers and service calls are routine.
What is a SIM-based dialer and how is it different from cloud telephony?
A SIM-based dialer places calls from the SIM in the user's own phone, so the customer sees a normal mobile number and the call costs whatever the operator plan charges. Cloud telephony routes calls through a virtual number on a server and bills per user plus per minute, in return for features like IVR and recording. For outbound sales on mobile numbers, SIM calling gets answered more often and costs far less.
Why do customers not answer calls from virtual numbers?
Because caller ID apps and phone dialers increasingly flag pooled virtual and VoIP numbers as spam or business calls, and because the same virtual number is often used for many campaigns. A real mobile number from a local SIM looks like a person calling, which is why SIM-based dialers report higher connect rates in India.
How do I stop my business number being marked as spam?
Call from a real SIM rather than a pooled virtual number, keep daily volumes reasonable, do not call DND numbers with offers, save your business name in Truecaller and similar caller ID apps, and send a WhatsApp before or after the call so the customer recognises you. Numbers get flagged by patterns of unanswered cold calls, not by calling your own enquiries.
What are the rules for business calling in India (TRAI DND)?
TRAI's commercial communication rules cover promotional and telemarketing calls: do not call numbers registered on DND with offers, use the 140 series if you run bulk telemarketing, and stop when asked. Calling your own enquiries, customers and service contacts is not telemarketing. Keep records of consent and be reachable on the number you call from.
क्या ऑटो डायलर से कॉल करना कानूनी है?
हाँ, अपने ग्राहकों और इन्क्वायरी को कॉल करने के लिए। ऑटो डायलर सिर्फ SIM से कॉल लगाने का तेज़ तरीका है, इसलिए वही नियम लागू होते हैं जो हाथ से कॉल करने पर: DND रजिस्टर्ड नंबरों पर ऑफर के लिए कॉल न करें, कोई मना करे तो रोक दें, और TRAI के कमर्शियल कॉलिंग नियम मानें।
What is an auto dialer app?
An auto dialer app calls a list of phone numbers one after another so the caller never types a number. On Android, an app like RMDialer runs the session on the phone itself using the SIM already in it: you pick a list from Excel, a Google Sheet, an API or assigned leads, press start, and the app dials each number in turn while you mark the outcome between calls.
Does RMDialer work on iPhone?
No. RMDialer is an Android app because iOS does not let a third-party app replace the phone dialer, read the call log or place calls automatically. It supports Android 8.0 and above. The owner's Web CRM works in any browser, including Safari on a Mac or iPhone.
Which languages does the RMDialer app support?
The app itself runs in 40 languages, including Hindi, Bengali, Tamil, Telugu, Marathi, Gujarati, Kannada, Malayalam, Punjabi, Odia and Assamese for India, and Arabic, Bahasa, Tagalog, Swahili, Portuguese, Spanish, French and others for teams abroad. Each user picks their own language on their own phone.
