NTT DoCoMo Inc. said Friday it has solved a technical problem at base stations that prevented its P503i Hyper mobile phones from receiving incoming calls and e-mails in some areas.

The nation's dominant mobile phone service provider said in July the glitch was causing disruptions every seven to 20 minutes in about 100,000 P503i handsets, supplied by Matsushita Communication Industrial Co.

Having solved the glitch, NTT DoCoMo said it will terminate a program launched after the glitch appeared to replace software in the handsets free of charge.

Some 800,000 P503i units have been sold in Japan since the model was released in January, the company said earlier.
