a Tmobile should have a sim card reader where they can put both sims in and they copy from one to another. That's been my experience Even the Micro sim card should work. If not, do you have them backed up to tmobile.com? If you do you can export them to gmail etc.
- Log in to My T-Mobile and then mouse over MobileLife and click Contacts.
- When the page loads with all contacts, click Print Contacts.
- Press and hold CTRL + A on the keyboard to highlight everything.
- Press and hold CTRL + C to copy
- Open Microsoft Excel.
- Click the first cell (for Column A and Row 1). Right-click and select Paste.
- Verify that the pasted information with details in multiple columns.
- Note: When you see the entries like 1.8E+10, this is normal since the cell is smaller then the information in the cell. If you want to see all the information you can expand the width of cell but it is not necessary.
- Right-click the letter A (the entire first column) and select Delete to remove the column.
- If there is no content in Row 1, right-click the number 1 (the entire first row) and select Delete to remove the row.
- Click the Cell for Column E, Row 1 and type Mobile Phone (use the capitalization shown here).
- Check that the excel sheet looks like the excel sheet in the image below.
- Perform one of the following:
- On older versions of Excel, click File at the top and then Save as.
- On Excel 2007, click the Office icon, then Save As, then Other Formats.
- Name the file (such as address book).
- In the Save as type field, select CSV (comma delimited).
- Browse to a location you will remember (like your Desktop) and click Save.
- If an error message apprears, click Ok or Yes.
- Instruct the customer to log in to their Gmail account and then click the Contacts option (on the left).
- Click Import (top left).
- Click the Browse button to select the Excel file you saved and then click Import.
- Note that Gmail automatically merges duplicates together and all MobileLife Contacts are now available on Gmail.
Do NOT cut your old SIM card, due to the high risk of error, that's a surefire way to eliminate your options to get the contacts off the old SIM card and onto your new phone/SIM card.
As andrew_g noted, you can use the steps he provided to manually transfer your contacts out of MobileLife into Gmail, which does work.
I would recommend that you import your contacts from MobileLife onto your old phone, then try the Contacts Transfer app on the Nokia Lumia (uses bluetooth) to transfer those contacts over to your Nokia Lumia. That method is extremely easy.
If for whatever reason that does not work for you, you can go into a T-Mobile retail store and have them transfer the contacts off your old phone memory onto the phone memory in your Nokia Lumia using a special unit that is designed to transfer contacts.
I put the old sim in my old phone then I just went into my Windows Live account on my computer, manually transfered all of my contacts onto that. (Took about 10 mins, on a computer keyboard its sooo much faster) Then synced my info into my phone. Done and done, then I linked my FB contacts with the contact info from my Windows Live account. Same with twitter.
I already cut my old sim, in half . I hope I don't need it again...
I have to point out one thing:
Of all of the technical and non-technical responses, no one has asked lvz2read what model phone he has...
I don't think I missed it, but it is important to know which phone he has in order to help him - don't you think?
Now that is out of the way, lvz2read, please let us know what phone you have, and perhaps I could help you.
