Who is 8x8 Best For?
8x8’s X2 and X4 plans work well for companies with high international call volumes, as those plans support 14-country and 48-country free-calling areas, respectively. Between them, the better fit for your company depends on where you call most frequently, and if those countries are covered under the X2’s 14 countries or the X4’s 48 countries.
Why We Picked Them

Who is Grasshopper Best For?
Grasshopper is best for US-based small businesses seeking a basic phone system. Their pricing structure offers budget deals for companies who plan to share 5 or fewer phone numbers among 6-20 users.
Users may be disappointed that Grasshopper lacks key routing features and communication channels, like IVR and team chat.
Why We Picked Them
Grasshopper offers an easy-to-use virtual phone system, basic phone features, and small-business-friendly pricing structures that potentially work out to under $10 monthly per user.
But companies making frequent international calls should consider an alternative because Grasshopper does not offer a large unlimited calling area.

Why We Picked Them
We picked Zoom Phone because they offer a complete phone system and unique domestic calling options around the world.
How to Make International Calls with VoIP
To call a landline, mobile phone, or VoIP number internationally, use the following process:
- Dial your country’s exit code: In the US and Canada, this is + (plus sign) or 011. Most other countries use 00 as the exit code
- Dial the destination’s country code: If calling a US or Canada number, the country code is 1. Other countries have their own code, listed here.
- Dial the recipient’s area code: Part of the phone’s 10-digit number, the area code changes by city or region
- Dial the recipient’s 7-digit number
| Example Call | Exit Code | Country Code | Area Code | 7-Digit Number |
| US to London, UK | 011 (US) | 00 (United Kingdom) | 020 (London) | 315-8783 |
| India to Panama City, Panama | 00 (India) | 507 (Panama) | 850 (Panama City) | 547-6589 |
How to Choose a Provider for International VoIP Calls
The best provider for international VoIP calls depends on your company’s business needs. Some of the providers listed above emphasize collaborative UCaaS features like video-conferencing, file-sharing, and team chat, while others emphasize routing features or a wide unlimited calling area.
When picking a provider, consider the following:
- Unlimited calling area: Some providers only offer unlimited calling within the United States and Canada. Some include Mexico, while some offer international calling options in over 50 countries. Consider where you call, and how often, to evaluate how large of an unlimited area you need.
- Phone number offerings: Some of the above providers only offer business phone numbers from area codes within the US, while some provide international numbers. If you want to establish an overseas presence, consider a provider that offers virtual phone numbers in your desired country.
- Routing and queuing features: Some of the providers listed above offer diverse routing and queueing features–IVR, hold queues, ring groups, and custom ring styles–that transform your phone system into a call center. Alternatively, some providers don’t offer any of these features. Consider your inbound call volume to determine if you want advanced routing features.
- Channel offerings: Consider your team’s internal collaboration needs to decide if you want a phone system that offers team chat and video conferencing. Even further, determine if you want to prioritize advanced collaborative features, like whiteboards and file sharing.
