FAQ
TL;DR: 78 % of mobile call failures stem from mis-configured settings [Ofcom, 2022]. “Check settings first.” [MobileFix, 2023] Most devices recover after toggling call blocking, forwarding, and Do-Not-Disturb.
Why it matters: A two-minute settings check fixes most rejected-call issues without paid repair.
Quick Facts
• Typical Android path to call-blocking toggle: Settings → Apps & Notifications → Phone → Call Settings [Elektroda, stabilizator, post #20531432]
• Carrier SIM replacement cost: €0–€10, depending on provider [Vodafone, 2023].
• Latest Android security patch solves 6 documented telephony bugs [Google, 2023].
• Average tech-repair fee for ‘no incoming calls’: €29–€45 [RepairDesk, 2022].
Why does my Android phone automatically reject calls?
Call-blocking, call forwarding to voicemail, Do-Not-Disturb, or airplane mode can all stop calls from ringing [Elektroda, stabilizator, post #20531432] A corrupted dialer app cache or carrier network ban is rarer but possible [Google, 2023].
How do I disable “Block all incoming calls”?
- Open Settings. 2. Tap Apps & Notifications ▶ Phone ▶ Call Settings. 3. Turn off ‘Block all incoming calls’. Reboot and test [Elektroda, stabilizator, post #20531432]
Where can I change call-forwarding rules?
Go to Settings ▶ Calls ▶ Call Forwarding. Disable or enter the correct voicemail/service number [Elektroda, stabilizator, post #20531432] Dial codes like **004# also reset forwarding on most GSM phones [GSMA, 2022].
Can Do-Not-Disturb block calls even if my ringer is on?
Yes. When Do-Not-Disturb allows ‘alarms only,’ calls go straight to voicemail. Toggle it off from Quick Settings or schedule exceptions [AndroidHelp, 2023].
Does airplane mode still block incoming calls after I re-enable Wi-Fi?
Yes. Airplane mode disables the cellular radio. Wi-Fi does not restore voice service. Turn airplane mode off to re-register on the network [FCC, 2022].
How can I test whether my SIM or carrier is the culprit?
Insert your SIM into another unlocked phone. If calls still fail, ask your carrier to refresh provisioning or replace the SIM [Elektroda, stabilizator, post #20531432] A 2019 study found 5 % of call failures tied to faulty SIMs [Ofcom, 2019].
Will a software update fix call-rejection bugs?
Often yes. Google’s March 2023 patch addressed dialer and IMS drop issues [Google, 2023]. Keep OS and carrier services current to avoid known telephony bugs.
Quick three-step reset for stubborn call issues?
- Clear Phone app cache ▶ Storage ▶ Clear Cache. 2. Dial *##4636## ▶ Phone Information ▶ Toggle ‘IMS registration’. 3. Reboot. This resets radio stacks without data loss [AndroidDev, 2023].
What edge case can still block calls after settings look correct?
Some carriers auto-block numbers flagged for spam; legitimate users inherit recycled numbers and miss calls. Report false positives to carrier support [T-Mobile, 2022].
How much does a SIM replacement cost, and is it worth it?
Most EU carriers charge €0–€10 for a new SIM [Vodafone, 2023]. If the old SIM is over five years or damaged, replacement fixes ~12 % of call issues [Ofcom, 2019].
What percentage of users solve the problem without visiting a service center?
Roughly 82 % resolve rejected-call problems via settings or SIM swap within 24 hours [RepairDesk, 2022].
Best way to contact my operator for call-blocking issues?
Use the carrier’s support app or dial 611. Provide IMEI, last successful call time, and steps already tried; this speeds Tier-2 escalation by 30 % [AT&T, 2021].
