The +677 country code is for the Solomon Islands, a sprawling archipelago of nearly 1,000 islands in the South Pacific, east of Papua New Guinea and northwest of Vanuatu. The capital Honiara sits on Guadalcanal, which is also known for its intense World War II battles. The population is about 720,000, spread across six main island groups.
The Solomon Islands is one of the least urbanized countries in the Pacific — most people live in rural villages on outer islands with limited infrastructure. Telecommunications coverage has improved since mobile networks arrived in the mid-2000s, but many outer islands still rely on satellite phones or have no coverage at all. International calls are expensive by global standards, which is why VoIP services are popular among the diaspora.
Quick answer: The Solomon Islands country code is +677. Local numbers are 7 digits with no area codes. There is no trunk prefix. Mobile numbers start with 7 or 8. Landline numbers start with 2 (Honiara) or 6 (provinces).

Understanding Solomon Islands phone numbers
All Solomon Islands phone numbers are 7 digits. The first digit tells you whether it is a mobile or landline.
Mobile numbers
Mobile numbers start with 7 or 8 and are 7 digits long. Our Telekom mobiles typically start with 74, 75, 76, or 77. bmobile numbers often start with 84, 85, or 87. A mobile number looks like +677 741-2345.
Landline numbers
Landline numbers start with 2 (Honiara and Guadalcanal) or 6 (provincial areas). Honiara government offices and businesses use 2X-XXXXX numbers. Provincial landlines (Western Province, Malaita, etc.) start with 6. A Honiara landline looks like +677 215-6789.
Number length
All numbers are exactly 7 digits. The Solomon Islands expanded from 5-digit to 7-digit numbers in 2018. If you find an old 5-digit number in a directory, it will not work — you need the updated 7-digit version.
Mobile carriers in Solomon Islands
Our Telekom
Our Telekom (Solomon Telekom Company Limited) is the larger of the two carriers, providing landline, mobile, and internet services. They are majority government-owned and operate the country's fixed-line infrastructure. Mobile coverage reaches Honiara, provincial capitals, and some rural areas on the larger islands. They launched 4G LTE in Honiara in 2019.
bmobile
bmobile (a subsidiary of Papua New Guinea's bmobile-vodafone) is the second mobile carrier. They entered the market in 2010, breaking Our Telekom's monopoly and driving down prices. bmobile's coverage is concentrated on Guadalcanal, Malaita, and Western Province. Outer islands have spotty coverage from both carriers.
Don't confuse +677 with nearby codes
The +677 code sits among several Melanesian and Pacific codes in the 67X range.
| Code | Country | How to tell apart |
|---|---|---|
| +677 | Solomon Islands | 7-digit numbers, Melanesian archipelago east of PNG |
| +675 | Papua New Guinea | 8-digit numbers, much larger country to the west |
| +676 | Tonga | 5-7 digit numbers, Polynesian kingdom far to the east |
| +678 | Vanuatu | 7-digit numbers, Melanesian neighbor to the southeast |
The easiest mix-up is +677 (Solomon Islands) and +678 (Vanuatu) since both are Melanesian nations with 7-digit numbers and similar area codes. Check the country code carefully — one digit makes the difference.
Time zone considerations
The Solomon Islands use SBT (Solomon Islands Time), UTC+11 year-round with no daylight saving time.
| Your location | When it is 10:00 AM in Solomon Islands |
|---|---|
| US East Coast (EST) | 6:00 PM previous day |
| US West Coast (PST) | 3:00 PM previous day |
| Australia East (AEDT) | 10:00 AM (same during AU summer) |
| New Zealand (NZDT) | 12:00 PM (2 hours ahead) |
| Papua New Guinea (PGT) | 9:00 AM (1 hour behind) |
The 16-hour gap from the US East Coast means your best window for calling during Solomon Islands business hours is your late afternoon or early evening the day before. Australia is the closest major time zone match.
Communication in Solomon Islands
Business hours
Government offices operate 8:00 AM to 4:30 PM Monday through Friday. Banks close by 3:00 PM. Honiara's central market and shops are busiest in the morning. English is the official language, but Solomon Islands Pijin (a creole English) is the common spoken language. Over 70 indigenous languages are spoken across the islands.
Network quality
Honiara has 4G LTE from Our Telekom and 3G from bmobile. Provincial capitals on Guadalcanal, Malaita, and Western Province have 3G coverage. Many outer islands — especially in Temotu, Rennell and Bellona, and Choiseul provinces — have no mobile coverage at all. The Solomon Islands connects internationally via the Coral Sea Cable (completed 2020), which replaced slow and unreliable satellite links. Call quality in Honiara is reasonable, but rural calls can drop or have significant delay.
Communication habits
In rural areas where phone coverage is limited, people still rely on HF radio and word-of-mouth. In Honiara and connected provincial towns, Facebook and Messenger are widely used. Prepaid mobile credit is the norm — most people top up small amounts regularly. International calls are a luxury for many Solomon Islanders, which makes VoIP services popular for those who can access internet.
The Solomon Islands diaspora
Where they went
The Solomon Islands diaspora is small compared to Polynesian nations. The largest overseas communities are in Australia (especially Brisbane and Cairns in Queensland), New Zealand, and Papua New Guinea. Some Solomon Islanders work in seasonal labor programs in Australia and New Zealand, which has created new calling patterns between rural villages and overseas work sites.
Why they call
Family and wantok (clan/kinship network) obligations drive most calls. Deaths, land disputes, bride price negotiations, and church events all require coordination. Seasonal workers in Australia call home regularly — sometimes the only phone in a village belongs to someone with a relative earning money abroad. Remittances are a growing part of the economy, and the phone calls to arrange transfers happen frequently.
Dialing examples
Calling a Honiara hotel from the US
The hotel's number is 215-6789. From a US mobile, dial +677-215-6789. From a US landline, dial 011-677-215-6789.
Calling a Solomon Islands mobile from Australia
The mobile number is 741-2345. From an Australian mobile, dial +677-741-2345. From an Australian landline, dial 0011-677-741-2345.
Calling from Papua New Guinea
The number is 215-6789. From PNG, dial 05-677-215-6789 (05 is PNG's international access code).
Calling within the Solomon Islands
For local calls, just dial the 7-digit number: 741-2345. No country code or prefix needed. Inter-island calls within the Solomon Islands use the same format.
Common mistakes to avoid
Using old 5-digit numbers
The Solomon Islands switched from 5-digit to 7-digit numbers in 2018. If you have a number from an old business card or directory, it will not connect. You need the updated 7-digit version — check with the person or look up the business online.
Confusing +677 with +678 (Vanuatu)
Both are Melanesian neighbors with 7-digit numbers and sequential country codes. One digit wrong sends your call to the wrong country. Double-check: 677 is Solomon Islands, 678 is Vanuatu.
Expecting coverage everywhere
The Solomon Islands has nearly 1,000 islands, but mobile coverage only reaches a fraction of them. If you are trying to reach someone on a remote outer island, they may only have access to a phone when they travel to a provincial town. Plan accordingly and try multiple times if calls do not connect.
Forgetting the time difference
At UTC+11, the Solomon Islands is 16 hours ahead of the US East Coast. A noon call from New York reaches the Solomons at 4 AM the next day. Call in your afternoon or evening to catch business hours.
