यहाँ "बिना शर्त" का वास्तव में क्या मतलब है
बिना शर्त कॉल अग्रेषण प्रत्येक आने वाली कॉल को बिना किसी अपवाद के, तुरंत दूसरे नंबर पर रीडायरेक्ट करता है - व्यस्त होने पर नहीं, अनुत्तरित होने पर नहीं, कवरेज से बाहर होने पर नहीं। यह "हमेशा" सेटिंग है, और यह भ्रम पैदा करने की सबसे अधिक संभावना है, क्योंकि इस तरह से अग्रेषित कॉल कभी भी मूल फोन पर नहीं बजती है।
यह मार्गदर्शिका बताती है कि इसे सशर्त अग्रेषण से क्या अलग बनाता है, सक्रियण कोड जो इसे सीधे नेटवर्क के माध्यम से चालू करते हैं, और लोगों द्वारा वास्तव में उपयोग किए जाने वाले उपकरणों पर सेटअप चरण।
बिना शर्त बनाम सशर्त: वह अंतर जो मायने रखता है
बिना शर्त अग्रेषण एक बार सक्रिय होता है और मैन्युअल रूप से बंद होने तक प्रत्येक कॉल के लिए सक्रिय रहता है। मूल फ़ोन कभी नहीं बजता - प्रत्येक कॉल सीधे अग्रेषित गंतव्य पर जाती है।
सशर्त अग्रेषण केवल एक विशिष्ट परिस्थिति में सक्रिय होता है: जब लाइन व्यस्त हो, जब निर्धारित संख्या में घंटी बजने के बाद कोई उत्तर न हो, या जब फोन पहुंच योग्य न हो (बिजली बंद हो या कवरेज से बाहर हो)। इन तीनों स्थितियों को बिना शर्त अग्रेषण से अलग से नियंत्रित किया जाता है, और एक फ़ोन में एक साथ कई सक्रिय हो सकते हैं।
अंतर मायने रखता है क्योंकि एक को बंद करने से दूसरे को स्पर्श नहीं होता है - फोन की समस्या का निवारण करने वाले किसी भी व्यक्ति के लिए भ्रम का एक सामान्य स्रोत जो अभी भी केवल एक प्रकार को अक्षम करने के बाद कॉल को पुनर्निर्देशित कर रहा है।
सक्रियण कोड
दुनिया भर के अधिकांश जीएसएम नेटवर्क पर, बिना शर्त अग्रेषण को किसी भी ऑन-स्क्रीन मेनू से स्वतंत्र, स्टार कोड का उपयोग करके सीधे नेटवर्क के माध्यम से नियंत्रित किया जाता है:
- सक्रिय करें: डायल
*21*[destination number]#और कॉल दबाएँ. - रद्द करना: डायल
##21#और कॉल दबाएँ. - स्थिति जाँचिए: डायल
*#21#and press call — the screen shows whether it's active and which number calls are being sent to.
These codes work on the network level, which means they function even on phones where the setting is buried in a confusing menu or missing entirely. They come from the standard call-forwarding MMI codes built into the GSM network layer, for anyone who wants the technical background.

इसे iPhone और Android पर सेट किया जा रहा है
On iPhone: open Settings, then Phone, then Call Forwarding, then toggle it on and enter the destination number. This maps directly to the *21* code above, just through a menu instead of a dialed code.
On Android: open the Phone app, tap the three-dot menu, go to Settings, then Calls, then Call Forwarding, and select "Always forward" (wording varies slightly by manufacturer). Enter the destination number and confirm.
If either menu path doesn't work — which happens more often on carrier-locked or CDMA devices — the *21* star code works directly through the network regardless of what the phone's own settings show.
जहां वास्तव में बिना शर्त अग्रेषण का उपयोग किया जाता है
Temporary full redirects. Forwarding every call to a personal or backup number while a business line is unattended — during a closure, a move, or before a new system is fully set up — is the most common legitimate use.
Testing a new number before switching over. Businesses migrating to a new number sometimes forward the old one unconditionally to the new line during a transition period, so callers on the old number reach the right place without needing to know anything changed.
Multi-location routing. A single published number can unconditionally forward to whichever location is actually staffed that day, which is one of the simpler routing patterns available before setting up a full auto-attendant or IVR menu.
Businesses running this kind of setup at any real scale typically move it into a UCaaS (Unified Communications as a Service) platform — a single cloud system for calling, messaging, and video — where forwarding rules can be managed centrally across every line instead of dialing star codes on individual phones, the same shift covered in our guide to turning off call forwarding for the reverse case. My Country Mobile handles this kind of centralized call routing for business numbers. Contact us to set up forwarding rules across a full team rather than device by device.
एक गलती जो सबसे ज्यादा भ्रम पैदा करती है
Turning off unconditional forwarding does not touch conditional forwarding, and vice versa — they're controlled independently even though both fall under the umbrella term "call forwarding." Anyone troubleshooting a phone that's still redirecting calls after disabling one type should check all four settings (unconditional, busy, no-answer, unreachable) rather than assuming one cancels the rest.
निष्कर्ष
Unconditional call forwarding is the simplest of the forwarding types conceptually — every call, no exceptions — but it's also the one most likely to get left on by accident, since nothing on the original phone indicates it's active beyond the setting itself. The *21* and ##21# codes work reliably across GSM carriers regardless of what a phone's menu shows, which makes them worth knowing even for anyone who normally manages forwarding through settings instead.
चाबी छीनना
- Unconditional forwarding redirects every call immediately — the original phone never rings at all while it's active.
- It's controlled independently from conditional forwarding (busy, no-answer, unreachable), so turning off one doesn't affect the others.
- The
*21*[number]#code activates it,##21#cancels it, and*#21#checks its status on most GSM networks. - Common legitimate uses include temporary redirects, number migrations, and multi-location routing.
- At business scale, centralizing this in a UCaaS platform replaces manually dialing star codes on individual phones.

पूछे जाने वाले प्रश्न
What does "unconditional" mean in call forwarding?
It means every incoming call is redirected immediately with no exceptions — not just when busy or unanswered. The original phone never rings while it's active.
What's the code to turn on unconditional call forwarding?
*21*[destination number]# activates it on most GSM networks. ##21# cancels it, and *#21# checks whether it's currently active.
Does turning off unconditional forwarding also turn off conditional forwarding?
No. They're controlled independently. Turning off unconditional forwarding leaves any active conditional settings (busy, no-answer, unreachable) untouched.
Will the caller know their call was forwarded unconditionally?
Usually not. The call connects to the forwarding destination with no notice to the caller in most cases.
Can I set up unconditional forwarding without codes, using just my phone's settings?
Yes. Both iPhone and Android have a menu-based toggle for this that maps to the same underlying network setting as the *21* code.
Why would a business want every call to unconditionally forward somewhere else?
Common reasons include a temporary closure, migrating to a new number during a transition, or routing a single published number to whichever location is staffed that day.
