My colleague used Global Telecom Testing for his new mobile app in 89 countries. I used to rely automated testing but he told me about GTT and I was surprised to learn that GTT uses live testers. I had them test my toll free number list of 2,900 numbers and I got back a 100% accurate result, even in countries like Bangladesh, Latvia, the UK, Nicaragua, Ghana, Bahrain, Korea, and Croatia. Thank you Stephen Levenson for your terrific service.
GTT has local testers in all the countries I wanted to test in and I was able to get accurate results for my mobile apps and toll free phone numbers. First I used their automated testing system to save some money. The gave me credits for failed calls and then I used their inn country international human testers for the rest of the numbers to get complete accurate results. Their mobile app testing service was great too as the actually had professional testers in each country I tested in.

When we test Israeli phone numbers, completion time depends on how the test is delivered. Israel is supported on our automated testing platform, allowing many standard validations to run in minutes. These automated tests are commonly used for reachability, routing verification, and basic call functionality. If a project involves live in-country testing, such as extended IVR flows or multi-scenario validation, execution may take several hours. We confirm realistic timelines after reviewing the number types, test scope, and delivery method selected.
Yes. Our Israeli telecom test results are generated through real testing on local networks using live devices. We place actual calls and send messages rather than relying on simulated environments. This approach aligns with internationally accepted telecom testing practices and supports consistent comparison across global markets. By capturing real network behavior within Israel, including call routing and system response, our results provide dependable insight for international service validation, troubleshooting, and operational assessment across multi-country telecom deployments.
Yes. We support international call testing from Israeli phone numbers. Our testers place outbound calls from within Israel to destinations worldwide, allowing us to observe routing paths, call completion, and audio performance. This testing reflects how users in Israel place international calls using local carriers. The results provide visibility into outbound connectivity performance and help identify routing issues, call failures, or audio limitations that could impact international communication from Israel.
In Israel, we provide phone number testing, toll-free number testing, IVR testing, voice quality testing, SMS testing, and roaming-related validations. These services are delivered through our automated testing platform when applicable, combined with live in-country testing by local testers. Each test examines real dialing behavior, network response, system interaction, and call audio across Israeli telecom networks. Clients can request individual test types or combine multiple services to support launches, audits, or ongoing performance monitoring.
We test Israeli mobile numbers, landline numbers, toll-free numbers, and Universal International Freephone Numbers (UIFNs) that accept calls from Israel. Testing is performed using real outbound calls placed by in-country testers or through our automated platform when supported. Each number is evaluated for reachability, routing behavior, and functional response. This provides clear visibility into how Israeli numbers operate across local telecom networks and how services perform under real calling conditions.
We evaluate voice quality in Israel by placing live calls over local mobile and fixed networks across multiple carriers. During each call, our testers assess clarity, delay, stability, and overall listening experience. This method captures actual network behavior instead of synthetic measurements. When required, we also test IVR prompts and DTMF input during the call. The findings reflect how voice services sound to users calling Israeli numbers under everyday network conditions.
Yes. We provide SMS testing for Israeli phone numbers using real devices connected to local networks. Messages are sent to validate delivery and observe timing, routing, and message behavior under live conditions. This testing supports services that rely on SMS for alerts, notifications, or authentication workflows. By testing SMS delivery directly within Israel, we help clients understand how messages reach local users and identify delays or failures that may affect service performance.
Israel’s dialing structure is consistent nationwide, but network behavior can vary by carrier and coverage area. Our testing reflects these differences by capturing performance across Israeli telecom networks rather than focusing on city-specific dialing. Depending on project needs, we can organize results by carrier or testing location. This provides insight into how numbers and services perform across Israel’s telecom environment and supports focused analysis when performance differences appear between networks.
To place an international call from Israel, dial the exit code 00, followed by the destination country code and the full phone number. We use this dialing format during international call testing performed from Israel. Validating outbound dialing behavior allows us to confirm that calls originating in Israel connect correctly to overseas destinations using local network dialing conventions.
Local calls within Israel require the trunk prefix 0, followed by the area code and local number. Mobile numbers are dialed using the same trunk prefix format. We follow these local dialing rules during in-country testing to validate reachability and call behavior. Using the correct dialing structure allows accurate testing of how users in Israel place domestic calls across mobile and fixed networks.
Toll-free numbers in Israel typically begin with the prefix 1800. We test toll-free numbers by placing real outbound calls from Israeli networks to confirm accessibility and call completion. This testing supports organizations that rely on toll-free services for customer support or inbound communication within Israel.
UIFN numbers accessible from Israel are dialed using the international format 00 800, followed by the UIFN subscriber number. We validate UIFN accessibility by placing real calls from within Israel to confirm connectivity and call behavior. This testing confirms that international freephone services can be reached by callers in Israel under real network conditions.
