Question 1

How do I call the United States from the United Kingdom?

Question 2

What's the cheapest way to call the United States from the United Kingdom?

Callo's per-minute rate to United States is $0.020/min, billed by the second with no monthly fee, contract, or carrier roaming surcharge. For most callers in the United Kingdom, that's cheaper than calling cards, roaming on a United Kingdom SIM, or paid VoIP plans that bundle minutes you don't use.

Question 3

Do I need a SIM card or app to call United States?

Accepted Answer

No. Callo runs entirely in your browser — no app install, no United States SIM, no second phone number. The person you're calling in the United States doesn't need an app either: they answer on their normal landline or mobile.

Question 4

What's the dialing code for United States?

The international dialing code for United States is +1. From United Kingdom you would normally dial the 00 prefix then 1 and the local number — on Callo we handle the prefix automatically, so just enter +1 followed by the number.

Yes — both. Callo routes to landlines and mobiles in United States at the same per-minute rate of $0.020/min. Call quality is HD on the supported codecs and a typical connect time is two seconds.
