Can I Use My Cell Phone in Japan? Here’s how to get local phone service and data with JP Smart Call

Having a local phone number is indispensable to setting up your life in Japan. This is because it’s almost impossible to look for a job or apply for an apartment in Japan without one. Landlords and real estate agents in Japan generally require that you provide a Japanese phone number on rental applications, not just an email address or Skype ID.

However, it’s not cheap or easy to get a cell phone in Japan. As we’ve discussed in other posts, some of the major Japanese carriers now offer “no contract” cell phone plans, but the price of not signing up for a two-year contract is usually an eye-popping fee for even a basic calling plan.

So how can you get a local phone number without locking yourself into a long-term contract or paying an arm and a leg?

JP Smart Call

One excellent budget-conscious option is JP Smart Call.

You may have heard of JP Smart Sim, which we discussed in a previous post. JP Smart Call, brought to you by the same company (JP Mobile), is an extension of the JP Smart Sim service.

JP Smart Call is a SIM card service that will enable you to use your cell phone to make voice calls and download data, without having to sign a long-term contract.
