Choose international calling without a monthly commitment

For occasional calls, start by comparing prepaid credit. Then check what can renew: a calling plan, automatic top-up and a rented phone number are different purchases. A service offering subscriptions may also sell credit without one.

A deposit, a call charge and a monthly plan are different

Prepaid credit

  1. Add a deposit
  2. Calls use credit
  3. Check what remains

Calls deduct from your deposit. Check expiry and inactivity rules for the remaining credit.

Calling plan

  1. Plan renews
  2. Use included calls
  3. Check exclusions

Check renewal, included destinations and unused-minute rules.

Which account arrangement fits your calls?

  1. Airlophone

    Occasional outgoing calls in a browser

    Airlophone prepaid calling

    Outgoing calls spend credit you add to the account. Credit does not expire. Optional rented numbers have separate recurring charges; you do not need to rent an incoming number just to make an outgoing call.

  2. RebtelViber Out

    Keeping an existing calling app

    Rebtel Credits or Viber Out credit

    Both providers document credit as well as plans. Compare the credit product before assuming that a monthly plan is compulsory. Viber's credit inactivity rules differ from its unused plan-minute rules.

  3. Talk360

    Prepaid calls with voucher access

    Talk360

    Check its credit-purchase instructions and whether you can buy a suitable voucher where you are. Read the current inactivity rules as well as the destination quote. A prepaid payment does not by itself establish that credit lasts indefinitely.

  4. KeepCalling

    Calling through a regular phone

    KeepCalling Voice Credit

    KeepCalling distinguishes Voice Credit from monthly plans. Check the access route for your origin and any local-phone or toll-free access charge before depositing credit.

Before paying for an occasional call

Tick each item after checking it.

0 of 4 checks marked.

Checks reset when you reload.

Four settings to inspect before paying

First, confirm that checkout is buying credit rather than enrolling in a calling plan. Second, inspect automatic top-up settings, which can charge again when credit runs low. Third, check credit expiry or inactivity rules. Fourth, look for an optional phone number or other recurring service on the account. Save the receipt and the renewal terms.

Read Airlophone's credit rules

Compare the cost of your actual month

Write down the numbers you expect to call, connected minutes including queues, and the provider's rounding rule. With prepaid credit, some of your deposit may remain after that month. With a plan, check what happens to unused minutes and calls outside its included destinations. A deposit, remaining balance and recurring bill are not the same figure.

Check current Airlophone destination rates

Keep an existing plan until you check what it provides

Opening a second calling account does not cancel the first. Check your current provider or app-store subscription settings and whether an incoming number depends on the plan. If a plan fits regular calls you actually make, keep it in the comparison.

Compare the service you already use

Check the number you need to call

Check the quote, then sign in, add credit and allow microphone access. Part of a minute counts as a full one, including connected queues, menus and voicemail.

Questions

Does no subscription mean no further payments?

No. Prepaid calls spend credit and you may need to add more. Automatic top-up, optional number rental and a calling plan are separate settings that can create further charges. Check the checkout and account terms.

Are Rebtel and Viber Out subscription-only?

No. Their official material includes credit as well as plans. Compare the product you intend to buy rather than treating every account as a monthly subscription.

Does Airlophone require a rented number for outgoing calls?

No. A rented incoming number is optional and has separate charges. Outgoing calls require a signed-in account with funded credit, a supported destination, internet and microphone access.
