If you run an agency, a consultancy, a software studio or a trading business in the Gulf or Lebanon with American clients, the work is often the easy part. The phone is harder. Your client’s day starts when yours is winding down, and many Americans will not dial a +971, +966 or +961 number. Here is a phone setup that works around both, and the local rules to check before you rely on it.
When does your working day overlap with the US?
Late afternoon and evening. These are New York’s office hours, 9 a.m. to 5 p.m., in your local time:
| You are in | New York 9 to 5, US summer | New York 9 to 5, US winter | A good call window for you |
|---|---|---|---|
| Dubai | 5 p.m. to 1 a.m. | 6 p.m. to 2 a.m. | 5 to 8 p.m. summer, 6 to 9 p.m. winter |
| Riyadh | 4 p.m. to midnight | 5 p.m. to 1 a.m. | 4 to 7 p.m. summer, 5 to 8 p.m. winter |
| Beirut | 4 p.m. to midnight | 4 p.m. to midnight | 4 to 7 p.m. most of the year |
“US summer” runs from the second Sunday in March to the first Sunday in November, according to NIST. The UAE does not change its clocks (ITU), and neither does Saudi Arabia, so from Dubai and Riyadh US hours simply arrive an hour later in your evening from early November to mid-March. Beirut changes its clocks too, but on different dates from the US, so for a few weeks a year its window starts an hour earlier. The US time-zone clock shows today’s window for all three cities.
West Coast clients start three hours after New York: 8 p.m. in Dubai in the US summer and 9 p.m. in the winter, and about an hour earlier in Riyadh and Beirut. If they matter to you, plan one late evening a week for them. The best time to call US clients has more cities and the clock-change dates.
Check your weekend as well. If your week runs Sunday to Thursday, the US Friday is a working day you are off, and your Sunday is their day off. Name your working days in your greeting, so a Friday caller knows when to expect you.
Does an app-based US number work where you live?
The TripoSIM US Virtual Number runs in an app over Wi-Fi or mobile data, so it goes wherever your phone goes. That is also why local rules matter: on your network, a call on the number is an internet call.
- Rules differ by country. Before you rely on calls, check the rules on internet calling with your regulator or mobile operator, and keep a local line for calls at home.
Texts are a different case. A text from a US sender reaches your number in the US and shows up in the app over your connection, like any notification. Verification codes from apps arrive the same way.
If calls on the number are not allowed or do not work on your network, it can still give US contacts a +1 number with voicemail, and receive texts and codes. You return calls when you travel, or from a licensed calling app or your local line, knowing the client then sees a different number.
Wherever you are, test before you print the number anywhere. The ten-check reliability test covers calls in and out, a locked screen, Wi-Fi and mobile data, and voicemail.
What should your contact page say?
Your contact page sets what US callers expect. Keep it honest and specific:
- The number in full: +1, the area code and the 7 digits, with a tap-to-call link.
- Your hours in US time: “9 a.m. to noon Eastern” means something to a client in Boston. “5 to 8 p.m.” does not.
- “Call or email”, not “call or text”: the number receives texts from US and Canadian senders but cannot send them. Put your email right next to the number.
- Your real location: a New York area code makes you easy to call. It does not give you a New York office, so say where you are based.
Sample copy:
Call our US line: +1 (your number). We return calls Monday to Friday, 9 a.m. to noon Eastern. Leave a voicemail at any time. For written questions, email us at (your address).
The business contact checklist has the full list, including accessibility and what to do if you change numbers.
What should your voicemail greeting say?
Most of your US calls will arrive outside your window, so the greeting does a lot of work. Say your business name, the hours you call back in Eastern time, your email address, and what callers should leave: their name, number and what it is about. Voicemail messages can be up to 2 minutes, up to 30 a month, and are kept 30 days. The voicemail guide covers setup and checking messages.
How do you run a daily call-back routine?
- Fix the window. Pick one hour inside US office hours, on fixed days, and keep to it.
- Play voicemail first. Sort calls by urgency before you dial anyone.
- Call back from the app. Calls you make to US and Canadian numbers go out from your US number.
- Confirm in writing. A two-line email after each call gives both sides a record across time zones.
- Switch off at night. Turn on do-not-disturb and return late calls in your next window.
How many minutes does that take? Four calls a week of 15 minutes is about 260 minutes a month, inside the 300 minutes a month to the US and Canada. Each outgoing call is rounded up to the next full minute; unanswered calls are free. Calls clients make to you have a separate fair use of 300 minutes a month. If you go over, extra minutes cost $5 per 100.
What can’t the number do?
- No sending texts. It receives texts only.
- No 911. It cannot call 911 or any emergency service; keep your local line for emergencies.
- No calls out beyond the US and Canada. Calls out go to US and Canadian numbers only.
- Not a team line. It is one person’s line for personal and small-business use, and call centers are not allowed. One person can have several numbers, though, each with its own plan, for example one per brand.
The bottom line
From Dubai, call New York between about 5 and 9 p.m., depending on the season; from Riyadh and Beirut, start an hour or so earlier. Publish a +1 number with your hours in Eastern time and “call or email”, record a greeting that does the work while you sleep, and return calls in one fixed window. Check the rules on internet calling where you live, and test calls before you rely on them.
