Spam calls and texts are a daily irritation in Ghana: fake promos, loan apps chasing debts that are not yours, “you have won” texts and outright scams. You cannot stop them all, but you can cut most of them out.

Block a number (Google Phone app)

Many Android phones, including Pixel and newer Tecno, Infinix and other models, use Google’s Phone app. Google’s steps:

  1. Open the Phone app and tap Recents.
  2. Tap the call from the number you want to block.
  3. Tap Block / report spam and confirm.

Blocked numbers are declined automatically. Google’s Phone app also lets you manage the list in Settings → Blocked numbers, where you can block unknown callers (private or hidden numbers).

Samsung and other phone apps

Most phone apps work the same way: open the recent call, tap the menu or the info (i) icon, and choose Block. Look in the Phone app’s settings for “Block numbers” and options like “Block unknown/private numbers”.

Turn on caller ID and spam protection

Google’s Phone app has a caller ID and spam setting that warns you about suspected spam calls and can filter them. Look in Phone → Settings → Caller ID & spam. Other phone apps have similar options.

Block spam SMS

  • In Messages: open the conversation, tap the menu, and choose Block or Report spam.
  • MTN Do Not Disturb (free): to stop SMS from a sender, text Block and the sender’s name or short code to 1309 (for example “Block 1444”). To allow them again, text Allow and the name to 1309. Text Check to 1309 to see your blocked list.

Do not engage

  • Do not call back missed calls from strange international numbers: some are designed to charge you.
  • Do not press numbers during robocalls or reply “STOP” to obvious scam texts; it confirms your number is active.
  • Never share codes, PINs or personal details with callers. See how to spot a mobile money scam.
Being harassed by a loan app? Keep screenshots and report it to the Cyber Security Authority (292, WhatsApp 0501603111, report@csa.gov.gh) and to the police.

Common questions

Will a blocked number know I blocked them?

No. Your phone simply declines their calls. They are not told.

How do I stop promotional SMS on MTN?

Use MTN’s free Do Not Disturb service: text “Block” followed by the sender’s name or short code to 1309, for example “Block 1444”.

Can I block all unknown numbers?

Many phones let you block unknown or private numbers in the Phone app’s blocked numbers settings. Be careful: you could miss genuine calls from delivery riders or hospitals.

Should I report scam numbers?

Yes. Report them to your network and, for fraud, to the Cyber Security Authority on 292.
