Cheap International Calls on iPhone: How to Call Abroad with TELZ (2026 Guide)
Making a cheap international call on an iPhone used to mean dealing with confusing dialing rules, carrier restrictions, and unpredictable long-distance fees. In 2026, it’s much easier to call abroad if you use an internet-based calling solution designed for international calling.
TELZ (www.telz.com) is an app built to help you make cheap international calls from your iPhone using Wi-Fi or mobile data. This guide explains what you need to know to call iPhone numbers and landlines abroad, avoid common mistakes, and choose the most cost-effective method for international calling.
Do You Need Anything Special to Make International Calls on iPhone?
Your iPhone can place international calls by default, but whether the call connects—and how much it costs—depends on a few factors. If you want a cheap call abroad, it’s important to understand what can block or increase the price of traditional international dialing.
1) Your carrier must allow international calls
Many mobile carriers block international calling by default to prevent accidental charges, especially on prepaid plans or new accounts. If international calling is restricted, your call may fail even if you dial the correct number.
- Some carriers require you to enable international calling in your account settings.
- Some plans require manual activation through customer support.
- Some prepaid plans do not support international dialing at all.
Apps like TELZ can help you call abroad without relying on carrier international calling permissions.
2) You need a working connection
There are two common ways to call internationally on iPhone:
- Cellular international calling (carrier-based calling)
- Internet-based calling (Wi-Fi or mobile data through an app like TELZ)
If you want cheap international calls, internet-based calling is often the most cost-controlled option.
3) Your iPhone settings must be configured correctly
When traveling, calls may fail if your roaming or carrier settings are not updated. If you plan to use traditional calling, ensure your plan supports international service and that roaming settings are properly enabled where needed.
How to Make a Cheap International Call on iPhone with TELZ
TELZ simplifies international calling by handling much of the dialing logic inside the app. Instead of worrying about exit codes and carrier billing, you can place a cheap call abroad using Wi-Fi or mobile data.
Step 1: Install TELZ on your iPhone
Download TELZ from the App Store and create an account. No SIM replacement is required.
Step 2: Choose the country you want to call
Select the destination country inside the app. This reduces mistakes with country codes and formatting.
Step 3: Enter the phone number
Type the full number (mobile or landline). TELZ is designed to call real phone numbers, not only app users.
Step 4: Tap Call to connect
Press the call button to call abroad. The call connects using your internet connection, which can help reduce traditional long-distance fees.
How to Call Abroad on iPhone Without an App (Traditional Dialing)
If you prefer carrier-based international calling, you must dial the number in an international format.
Step-by-step: dialing international numbers
- Open the Phone app and tap Keypad
- Press and hold 0 to enter the + symbol
- Enter the country code
- Dial the full local number (including area code when required)
- Tap the green Call button
Examples:
- Mexico: +52 + local number
- USA/Canada: +1 + local number
- India: +91 + local number
This method works, but it is often not the most affordable way to get cheap international calls—especially when roaming charges apply.
Cheapest Ways to Make International Calls on iPhone in 2026
If your priority is making a cheap call abroad, these are the most common approaches users choose in 2026.

3) App-to-app VoIP calling (WhatsApp, FaceTime Audio, etc.)
These services can be free, but they usually require both people to have the same app and an internet connection. They may not work for calling landlines, businesses, or contacts using basic phones.
Common Mistakes When Trying to Call Abroad from iPhone
- Missing the “+” symbol when dialing manually, especially while traveling
- Forgetting the country code and assuming the number will connect automatically
- Assuming Wi-Fi Calling is free (carrier rates may still apply)
- Trying to use iMessage/FaceTime as a replacement for calling real phone numbers
