Standardize Phone Numbers: This is crucial. All numbers must be in a israel phone number list globally recognized format, including the international dial code (e.g., +1234567890 for a US number, +8801XXXXXXXXX for a Bangladeshi number). Do NOT include spaces, dashes, or parentheses.
Verify Accuracy: Even a single incorrect digit can lead to a failed delivery.
Handle Missing Data: Decide how to manage contacts with incomplete information (e.g., no name).
Step 2: Converting CSV to vCard (VCF) - The Universal Contact Format
While some phone systems can directly import CSV, the vCard format (VCF) is almost universally accepted for contact exchange across different devices and operating systems.

There are several online and offline tools that can convert your CSV to VCF. Popular options include:

Online Converters: Search for "CSV to VCF converter online." Be cautious and use reputable sites, especially with sensitive data.
Spreadsheet Software (e.g., Google Sheets, Microsoft Excel) with Add-ons/Macros: Some advanced users can write macros or use add-ons to export to VCF.
Dedicated Contact Management Software: Many CRM or contact management tools offer direct export to VCF.
When converting, ensure that the mapping of your CSV columns to the vCard fields is correct (e.g., CSV's "Mobile Number" maps to vCard's "TEL;TYPE=CELL").
This is where your phone's operating system comes into play.
Upload it to a cloud storage service (Google Drive, Dropbox) and download it on your phone.
Connect your phone to your computer and directly transfer the file to your phone's internal storage (e.g., Downloads folder).
Open the Contacts App:
Navigate to your phone's "Contacts" or "People" app.
