راهنمایی برای خرید ماژول gsm/gprs

[Mojtaba]

Gtm900b نمونه کد تست شده و پشتیبانی مناسب نداره..همه نمونه کدهای Sim900رو براش معرفی میکنن.. Sim900 حداقل شناخنه شدست و رفع اشکالش سریعتره..یک فروم تو اینترنت نیست که یک نفر با Gtm کار کرده باشه جز همین فروم که کسی پاسخگو مشکلات نمیشه.ما که از Gtm پشیمون شدیم.
